"Genuinely invokes the early days of human exploration"
9/10 - Eurogamer

"With beautiful artistic touches throughout and gameplay that doesn’t feel traditional at all, the experience that is MirrorMoon EP is one that will likely stick with me for years"

"[...] one of the most dazzling moments I’ve ever experienced in a game"
Indie Statik

"When I was a kid, I was deathly afraid of space. The stark, vast beauty of the night sky both entranced and terrified me [...] While I have long since overcome those fears, MirrorMoon brought the memories of them back with a vengeance. I have never played a game that captures the simple and dangerous beauty of space quite like it."

About This Game

MirrorMoon EP is a game about mystery and exploration set in outer space.
These space travels begin on a red planet and its unique moon and extend across galaxies.
The single player part of MirrorMoon EP blends adventure and exploration with navigation-based puzzle solving. The multiplayer of MirrorMoon EP lets players share Galaxy Maps with other players: the first explorers to land on a planet will be able to name its Star System and that name will be forever bound to the star for any other fellow traveler who encounters it.

Each Galaxy consists of a thousand Systems: it will be possible to fully discover the mysteries of MirrorMoon EP only while collaborating with other players.
Through the apparently indecipherable cockpit of an unknown spacecraft, players will be able to locate and travel to mysterious planets. Each planet has artifacts, buildings, and puzzles on its surface, hidden in astonishing low-poly sceneries.

MirrorMoon was nominated for the Nuovo Award for innovation in games at Independent Game Festival 2013 and was also part of the Official IndieCade and Fantastic Arcade 2012 selections. Since then, MirrorMoon has grown considerably. EP stands for Extended Play, representing all the new content that we added for the official release.

This game has such a cool atmosphere and style, it's painful to think how good it could have been. Sadly, the puzzles are annoying and unpleasant. A lot of randomly walking around with no idea what to do, and frustrating mechanics.

For example, you can't look around, you can only move using WSAD. There's a moon in the sky you can look at to figure out what's going on, the "MirrorMoon." Since you can't actually look upwards at the sky, you have to wander around until the curvature of the planet aligns you properly just to see this thing, and then try to memorize where to go before you blindly wander off looking for what to do next. A small task that should take 2 seconds becomes a huge chore. The whole time I was like "WHY CAN'T I JUST LOOK UP!?!"...

I tried to get further in this game and give it a chance, but I couldn't handle it for longer than an hour.

Do you like space? Exploration? Puzzles?
If so, this game might be for you. But it might not be.

Do you also like really vague goals? What about being dumped into an unfamiliar environment without any intrinsic help? Quiet emptiness? What about all that?
To many people the above might be very negative points, but I feel they together paint an interesting narrative.

This game doesn’t hold your hand. It refuses to stand in the same room as you. Doesn’t even look in your general direction. Remember that one puzzle near the end of Myst where you were in a cart and had to find your way out by choosing which way to go at every intersection? A different sound effect was played at every intersection, but without some serious trial-and-error there was no way to know that the sound that played corresponded with the direction you were supposed to go in. To solve it without help, not only did you have to somehow connect the sound effect to the direction, but you had to somehow sort out *which* sound effect corresponded to *which* direction. This game is a lot like that puzzle, only the answer isn’t published anywhere and you sure as hell can’t ask your dad for help.

I’ve landed on unnamed planets where there is nothing to do at all, the only thing present is the gate to get back on the ship. There are also planets where there are things to see, but no real puzzle to be solved. When there is a puzzle to be solved, it’s back to trial-and-error, but at least you have your prior experiences to go on this time. This game is slowly paced and doesn’t spoonfeed you—sometimes you find some neat stuff on a planet, but sometimes there is nothing. I mean, even that “nothing” planet gets you closer to your goal of “find that anomaly somewhere in the universe” but that isn’t what most people are accustomed to in a game.

The minimal sound effects/soundtrack is great, and I find the game itself quite relaxing. The only annoying bit is the “in media res”-type beginning. Just like when you needed help with that Myst puzzle, I suggest you look for help on Steam with guides/forums, as well as looking through youtube videos (or I guess you could just brute force it until something sticks, like those who mapped out that entire puzzle by hand, but that too could take a while). Once you’ve grasped the first tutorial planet, you should have an idea on how the game is played and what you should be looking for.

It's hard to rate this sort of thing. If you're anything like me, no negative review is going to stop you from buying, playing, and ultimately being disappointed anyway. I guess there's nothing wrong with that, and I can't say I regret playing this for the short time I did. It's fun to figure out the ship controls and learn to manipulate the moon artifacts, but once you do the game's pretty much over. The game just doesn't keep up that sense of discovery for very long.

You'd probably get more out of any hardcore space sim, or hell, any classic first-person or text-based adventure game like Myst or Zork. But like I said, if you're at all interested in this game, you're probably the kind of guy that won't give up hope until it's too late. So go ahead, buy it, you poor goofball.

This game could be good, but it's marred by two primary problems: terrible controls and tedious gameplay.

Wandering around the planets is not very interesting, since they're mostly barren, monochromatic worlds. I've seen reviews raving about the "gorgeous worlds" but simple polygon-based graphics, despite the uniqueness, doesn't equal gorgeous. You'll be looking for various structures, but since you can't really look around very well, and have to keep referencing the "mirrormoon" minimap in the sky, it's a hassle to find stuff, such that you'll pick a direction and hope it's the right way, but end up circumnavigating the entire globe and have to look at the minimap again.

And the controls are entirely obtuse. Navigating to other planets, well, good luck figuring that out, and even when you do, be preparing to spend five minutes trying to select a new location. All in all, you'll be wasting a lot of time just trying to do the most basic things. That's not my idea of fun. I don't need a lot of handholding necessarily, but I do need a game that is at least intuitive and sensible. I got this in a bundle, thank goodness, otherwise I'd be really annoyed.

I hardly write reviews, it's not my thing but I am really frustrated with this game... I thought it would be so fun but, oh, how mistaken I was... It's so annoying and frustrating. You will be walking on a surface of a celestial body in first person, where you can't look up nor down, just forward and to the sides, also you can't see very far too. It's pretty much like the Spore's worlds, but worse because it is empty and in a very smaller scale. There's no tutorial nor explanation of what you have to do. That means you will first be worried if your mouse is working correctly, since you can't look up and down, then you may think that it may be an issue with your gamepad, if it is plugged in. But then you will understand that this is just an annoying limitation for some reason.
Without knowing where to go or what to do, you will, eventually, discover that the celestial body up there is actually a map and by "upgrading" your, err, "gravitational gun" you can drag it around, which will also be a pain since you can't look up you will have to align yourself with it.

There's a map and a kind of travel machine that is really, really weird and a pain to use it properly. You will find yourself flipping switches without knowing what you may be doing, as always...

In sum, you will be aimless walking on a empty surface doing stuff that you are not sure what nor why.

I would not recommend this game to anyone, not even for its art.

This game realy inspires me.

I love the sense of mystery around it, at the same time it frustrates the hell out of me.
You just keep going, walking by faith that there is some big secret somewhere , and youl be a the first to find it, then name it.
The music is very beautiful and some of the graphical combinations you come across can be realy pretty.

The only downside is, some planets are too easy, and some are seemingly impossible to unlock/name.

Its also frustrating knowing its by faith you carry on, not being 100% sure of anything. At the same time, thats what makes it so good.

I've player this game for about an hour and I can already say that I love it. I understand how many people find it annoying or think it's not a real game, but artsy-farty rubbish, but that's not what I feel it is.
First of all, the graphics are amazingly different from any other graphics I've seen in any other game. They're neither hi-fi like most 3D-games nowadays nor lo-fi like, for example, antichamber. They remind me of a game site called Venus Patrol and I've always loved their design. The music reminds me of early islandic electro band mûm. The athmosphere alone is fantastic and alienating, maybe like the first Metroid game, but in a different, more subtle way.

Now, the game itself made me feel like a lab monkey that was submitted to a complex intelligence test. Where am I? What is all this? What shall I do. There is no reference to anything that could help me solve any of these questions, and, as a curious little labrat, I start pressing levers, turning knobs until Ifind myself on the surface of something, wielding something and advancing towards something.

If you need action and easy clues, the game is definitely not for you. If you love a weird-but-soothing athmosphere, uncommon puzzles and intersting graphics: give it a go. I really didn't regret it!

First, to put things into perspective this game wears a mustache, always has a beret, rides a bicycle, has a crazy contraption just to make coffee and only listens to garage bands because everything else is too mainstream. Second, were you ever asked to play a game, spend the next hour looking at each other and in the end of that hour the person asked: "do you know how to play the game?" and you answer "no, I thought you knew". That's this game for you: guessing what to do while spending time naming random solar systems until you finally strike luck and manage to finish the game. It's madness.

A procedrually generated space themed environmental puzzle game with a focus on exploration and navigation. Puzzles are procedurally generated and run the range of obvious and simple to clever and surprising. And sometimes even after the anamoly is solved there will still be things to do and discover on the planet, revealing easter eggs and other surprises. Once an anomaly is solved you get the right to name the star, as players explore the galaxy and solve anomalies the galaxy fills up with the unique signatures of various astronauts. This is a starkly beautiful game, evocative of the Italian underground indie freeware classic Noctis. The visual themes call back to Kubrick and Tarkovsky's work. This game is all about the journey.

This game is beautiful and i really want to like it.
there seemed to be some kind of story and coherency at the beginning, but as far as i know the game has no end and goes on forever, you endlessly explore randomly generated planets (the bad kind of randomly generated i.e empty feeling and seeing the same things on multiple planets) and give them a name once you've found a white orb, why and for what? once you've explored an entire galaxy you just rinse and repeat with a new galaxy. finding those damn orbs on those empty planets with simplistic puzzles

i like art and slow burning exploration games. but in this case i can't help but ask: is there even a point, a goal?
and from what i've read on forums there isn't. and if that's the case this game just might be 2avantgarde4me. i heard about some kind of anomaly that you can find though, and i've seen ringed-in stars in the sky, but it's impossible to triangulate their position based on the information you are given. and if finding the anomaly is the point of the game, the journey getting there is too bland and empty for me to want to bother

i'm all for mystery, no handholding and a "the journey is the goal". but this game just might take those to such an extreme that it comes off as pretentious, farfetched and frustrating, it took me hours to even figure out how the ship worked, (most of that time went to trying to calculate what the numbers on the screens meant, finally understood that they were parsecs, fuel and coords etc) i've read interviews and i know that they wanted the ship to be a mystery and something you have to figure out, but to me, making it a mystery seemed only to serve as a filler to extend gametime and keep you intrested. and understandably so, because learning to operate the ship is more fun than actually exploring the planets. not only because the planets feel empty, but because the cockpit actually is one of the strenghts of the game, it is very detailed and everything you see inside it has meaning and every button does something. which even real simulator games fail to do right, the cockpit in train simulator for instance is just a toy, you can only operate a few essential levers and buttons and the rest is just window dressing. train simulator should learn from mirrormoon's cockpit. it's good.

but ultimatly the game suffers the same problems the tv show LOST does, too many questions and too few answers and all filler and frustration inbetween, and the answers you do get are farfetched and/or hamfisted.

now you might just think i'm not very patient but there is a difference between slowburners and bad pacing: a slowburner is well thought out; on how it will be percieved by the consumers, what message it wants to deliver and WHAT message it wants to deliver. you can extend running time in a manner that doesn't feel like filler and ask questions and keep the answers away from the consumer without being annoying. take 2001 a space odyssey for example, or the game FRACT OSC. those are good because they have soul, an artistic vision, are well thought out and takes into account how it will be perceived and experienced. And since mirrormoon is randomly generated (at least i think so, otherwise the leveldesign just sucks) there is no thought and structure put into the progression of game. making it feel soulless and empty, mirrormoon's artistic vision is beautiful though, but the progression and gameplay is kind of like fumbling in the dark to find marbles and once you got them all you throw them out on the floor to do the same thing again. now that might sound like some kind of avant garde flashmob act, but is it fun? not to me at least.

I'm not going to lie, Mirrormoon was really irritating for me at first. I found myself rushing through the puzzles, jumping from planet to planet, trying desperately to figure things out, and usually with a negative result. But after awhile, I realized that Mirrormoon isn't about fast paced puzzle completion and bare bones "what you see is what you get" narrative. It's about discovery and exploration. Its subtlety and sublime beauty is what makes it great. The moment I let myself slowly get pulled into the massive scope of Mirrormoon is the moment things started making sense, and I began to truly appreciate what the game was trying to accomplish.

MirrorMoon EP is definitely an interesting exploration game. I like the visuals and the music, and the "mystery" concept is also quite intriguing, but it is so incredibly frustrating and tedious to navigate through the game.

While on a planet, I spend most of my time wandering around aimlessly on an almost empty surface. Often there's a big "map" in the sky in the form of a moon, but I can't look up at it, I can't look around me, and I can barely see a few feet in front of me.

While in space, there is a 3d map of the galaxy, but I can only scroll through the available destinations in a really tedious and error-prone way. There is a somewhat obtuse coordinate system for the planets (mystery!), which I wouldn't really mind, but there's no way to input coordinates or do anything other than scroll through the map.

The manual basically says that you have to cooperate with other players to find the end of the game, but from my experience, what they meant to say is that one person will stumble on it by accident and will maybe tell the others on the forum.

All in all, I'm trying to like this game, but it's just too frustrating.

It's really hard to recommend this game because it caters to such a specific taste. If you like to explore, I mean, REALLY explore; knowing full well that that your expeditions may not lead up to some uber-awesome, explode-y finish. If you really like the journey more than the destination and can appreciate very sparce---well, everything---this is worth checking out. For me, I love it. It's the closest thing I've ever come across in a game that creates, what I can only assume to be, a religious experience. It's exploration at its purest. If you've not the patience to take in hours upon hours of treking in barren landscapes, occasionally running into something odd and solving puzzles without any direction on how to do it: give this a go.

It's Proteus. In space. With less (and very different) music. What's not to love*?

*Replace "love" with "hate" if you think Proteus is an abomination of a non-game.

[there may be a bit of spoiler in this review] this game felt big and small at the same time. I wanted more from it, so the experience was ultimately unsatisfying. it does a great job of making you feel lost in the immensity space - and just plain lost - and the exercise of figuring out the ship's controls was interesting. the controls themselves, though, felt a bit awkward and limiting, both on board the ship and while on a planet's surface (e.g. a game about space and star mapping, but I cannot look up at the sky when standing on a planet surface? please!) this detracted from the puzzle solving aspect. not that the puzzle aspect was that great. from what I could tell, the game has a pool of puzzle components (tools you gather, alien artifacts, astronomical effects, etc.) which interact with each other in various ways, and each planet is a quasi random arrangement of these components. once you solve a planet's arrangement you are rewarded with the opportunity to name the planet/star system. although the game is about puzzle solving for the sake of puzzle solving, and exploring for the sake of exploring, there is a loose "final" goal of identifying, reaching and solving a specific planet (the Anomaly). maybe I got (un)lucky and was able to accomplish this goal fairly quickly, affecting my impression of the game. I only explored about a dozen planets (0% of the galaxy generated for me) when I reached the Anomaly. of those that I did explore, many had trivial solutions, or seemed unsolvable. too few were in the "happy medium" between these extremes, with worthy, interesting puzzles.

the graphics are minimalistic, eerie and in tune with the openness and emptiness of space, but quickly repetitive, each planet just a barren polygonal ball of some color, with a sun and a some "random" landscape features and puzzle artifacts. something as simple as varying textures would have made the experience more appealing. between this visual barrenness and the disappointing puzzle generation, there really isn't much to entice me to return to this universe. maybe those unsolvable planets are actually solvable, and I'm sure there are alien artifacts and puzzle elements I haven't seen yet, but it just doesn't feel enough is there to put up with the long blind search through space. ultimately I expected something like the game Antichamber but in space, with planets and space wonders instead of rooms to solve. it didnt live up to that, although I admire the concept behind this game.

(contrary to what I wrote above, I did give the game another try, this time on multiplayer, but the first thing I run into is the game forcing me to play the tutorial again. really? forget it)

I don't know how to do anything and it's amazing. I press a button and something happens. I press another button and nothing happens. Trial and error teaches me to pilot my spaceship. I am on a tiny planetoid. I grab the moon and make an eclipse.

I'm being vague and bewildering because this game is vague and bewildering and to explain it, if I could, would be to ruin it. Luckily I can't explain it, except that it's beautiful and strange and it reminds me of trying to figure out old DOS RPGs without a manual when I was eight.

If you like explorational puzzle solving this is a game you should buy.

I am slowly learning to travel in space.
Time is a meaningless variable that slips through my fingers.
Stopping requires a lot a energy while moving feels almost like staying still.

Breathing is hard inside the machine.
I need to stay calm.
