"[...] 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 is based on exploration, and traversing through space. It has a great style; but if you dont know what to do you are pretty much stuck on the spaceship menu thing. Not much besides the controls are explianed to you, as you learn through exploring the various planets.

This game is a very interesting one. I got it when it game out and was on sale, and decided to play it. The abstract art and music is very unique, in the fact that I have not seen it in many, or even any, other indie games. It is somewhat of a puzzle game too, tagged along by the concept of space exploration.

Overall, I would recommend this. It is a very different experience from most games you will find on Steam, and is well done as well.

[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)

beautiful environment to start with. the challenge is mostly figuring out how the game works. which is my favorite feature. I still can't figure out how to finish it though. so I'll give it a 7/10 realisticaly but 9/10 personally. because of the challenge.

I want to like MirrorMoon. I really do. The tutorial is great. The "real" game, however, is less than great.
It is supposed to be an art piece, about the journey and whatnot, and I get that. Most games like that, I enjoy. But this game gives you so little information about the endgame that it turns into a space exploration simulator where everything start to look the same. I am still trying to find the "anomaly" so I can say I beat this game, and it has turned into a chore. Finding new planets no longer excites me; the features are all the same. For 5 bucks, you might be intrigued for a little. Just don't plan on "finishing" MirrorMoon. You won't. Buy AntiChamber instead. It doesn't take place in space, and it is more expensive, but it is just as mysterious, and with just a little tutorial, and I have played it many times.

Simple but very very effective. Makes you really feel ike an astronaut looking for something. At the beginning is a little bit complicated to understand how it works because of the absence of a tutorial, but again that only improve the lonliness astronaut's sensation. And the grafic is very cool.

MA poi l'hanno pure fatto a Milano, lascia fa.

An amazing space exploration game, in the tradition of Myst where you must figure out both what and how. Fantastic art and truly abstract music, which blew me away and fits the game well.

The end game can get a bit tedious after you've figured out what's going on, but somehow it still keeps you sucked in until the wee hours of the morning.

This is a very, very very strange game. I don't mean that in a bad way, but I'm still not sure to what extent I mean it in a good way. I have 7 of 10 achievements, and I might (?) be approaching the final goal (?) but I still have no very clear idea what I'm doing. For example:

The Other Way Round: Lose the keys in SideA in a different order. I've got that achievement! Yay me! Ummm ... different from what? Was I losing keys in the same order before? I wasn't aware that I was "losing" anything, I thought I was putting stuff back. (In no particular order.) What are keys? They must be those coloured geometric thingies that give my gun-sort-of-thing different abilities.

Side A completion was at 50% the first time I noticed it, and it stayed there for many planets until it suddenly jumped to 95% ... and I hadn't noticed that I had done anything remarkable on that particular planet. Side B completion started off at 55%, I think, and has climbed all the way to 56%. Side A vs. Side B, and the purpose of each, is an interesting puzzle in itself. Some say that Side A is a "tutorial" ... unless my game is broken, it's a very strange tutorial indeed. Sort of a DIY tutorial?

This is a very, very very strange review. I guess that what I'm trying to say is that if you like the idea of a game where solving a puzzle is easier than solving the puzzle of what the puzzle is that you're solving, this is the game for you!

MirrorMoon EP is not a game that will hold your hand. You will not often be rewarded with feedback. You will feel frustrated and lost. You will think you are right, and then be proved wrong. I would not have it any other way.

This game is about searching, failing, and floundering for understanding. If you give up easily, this isn't the game for you. The less you know when you begin, the more profound your journey will be.

Seek the anomaly.

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.

OK, I bought this game a couple days ago and started by putting a couple hours on it. I made it through Side A (basically the tutorial) and visited a few stars in Side B (the main game). If I had written the review at that point it would have been a fairly negative one. The next day I decided to have another go at it before writing a bad review. My intent was to only play an hour or so... I ended up spending basically the whole day and logged about eight more hours on it, lol. Needless to say, MirrorMoon had really grown on me and I had slowly fallen in love with this game.

I think my initial negative reaction was because I was expecting something more of a puzzle game along the lines of Kairo, which MirrorMoon is not. The A Side of the game is definitely a puzzle and there are some nice "ah-ha" moments when you first figure out how to do something. The game doesn't do much hand-holding and you're thrown into this mysterious world without even a clue as to what you are even doing. The "tutorial" part is only some very brief tips about the basic controls of the game (as in what keys do what). You are left to try to understand everything on your own and it works hugely to the advantage of this title. A huge part of the enjoyment of this game is the mystery of it all. A side note here: if you look an any guides about this game before playing you'll be doing yourself a terrible disservice.

In Side B you are left to explore the universe and I think the "puzzle" part of the game mostly ends here. Every star you visit will be a variation on the puzzles you've solved on Side A. Some take a few minutes to solve and sometimes the exit it literately right in front of you. You should already know how to solve them though and it becomes simply a matter of doing it. At first I found this tedious and repetitive... then I realized I was looking at this all the wrong way. If you approach each star as a problem to be solved I don't think you're going to enjoy it very much. The better approach is to look at each world as something to explore and experience. Just relax and enjoy the atmosphere (this game tons of it). Once I started looking at it from this point of view I found the game to be quite enjoyable.

The good: Simple but nice looking graphics, wonderful soundtrack, very atmospheric and mysterious universe to explore.

The bad: Not much variation on the look of the planets or the puzzles to be solved.

The ugly: I've had a few crashes. It's always just as I arrive at a star and the game closes without warning. Not a huge issue but it's annoying since it always starts me back at the star I started from instead of the one I just arrived at. It doesn't happen very often and I'm on the Linux version so it may not affect everyone.

So far, this game looks like it's going to be one of my favorite games of all time. However, I cannot say that it's perfect or spectacular without a lot of bias. This game happens to have just about everything I love in a game, so of course I really, REALLY like it, but it is not without faults.
The reason why I like this game so much probably has to do with my favorite attributes to have in a video game. They would be: exploration, puzzles, atmosphere, huge size (why I like games that use procedural generation so much, which this game has) and space.
So, what's good about this game:
-Very atmospheric. This game is so relaxing and calm, while also keeping that mysterious air. The 'artifacts' are all interesting to look at, and the isolated feeling this game brings is just niiiiice.
-Quite a bit of exploration. Each planet is unique, with lots of different artifacts to find.
-Interesting puzzle mechanics. I've never seen a game with mechanics quite like this one.
-Nice aesthetic. The colorful minimalist style is just really enjoyable to look at.
-Basically infinite puzzles to solve.
-The search for the 'Anomaly' as it's called, is really nice incentive. The very existence of the Anomaly gives this game a lot more purpose than it would have had otherwise.

What's not so good
-Not friendly to people just starting out; not much explanation is given as to what to do. The mechanics and stuff aren't too confusing, and one could figure out what to do by going on the Mirrormoon EP forum on Steam, but this is still quite a problem.
-If exploration isn't your thing, you probably won't like this game much, unless you really enjoy the puzzles. The main appeal of this game is split between the exploration/atmosphere (I'm lumping the two together) and the puzzles.
-The puzzles are a strange mix of confusingly abstract, and too straightforward. The tutorial puzzle and the anomaly both show just how amazing the puzzles in this game can be (and there are multiple anomalies, so don't worry about there only being two really good puzzles), but then the rest of the puzzles are kind of simple. I tend to be really good at puzzle games, so I encounter this problem to some extent in most puzzle games, but this one feels like it would be a little on the easy side even to someone who wasn't good at puzzlers. Maybe that's a good thing(?) but honestly, trying to say it's a good thing, when it is clearly a turn off for those looking for a mind bending puzzle experience, would be outright lying,
-I have heard of people despising the art style. Not going to lie, I think this is a stupid argument, because if you hate the art style THAT much, then you can see from the screen shots that the game won't be for you, but I can agree the art style is somewhat hit or miss. Most people I know like it, and think it looks pretty nice, but there are definitely those that hate it.

So, of course, I recommend this game. However, I have to point out flaws to be fair.

P.S. I've heard this game called 'pretentious' and 'a walking simulator' before, a few times. I think both comments are completely off base, as this game isn't pretentious at all, and calling it a walking simulator totally ignores the puzzles, you know, the main point of the game.

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.

I was excited by the solid style that this game seems to radiate from every screen shot and marketing image, but what really sold me was the engaging and addicting exploration. I became a space traveler... I learned to navigate the stars through trial and error. Space became meaningful to me. I am now an experienced astronomical navigator. Even making simple pit stops to check out an unnamed star system, that I knew wasn't a destination I was looking for, was really satisfying.

Yes, it's a little slow paced, it requires a little patience, but it rewards you for your curiosity. This game is serious fun, and incredibly beautiful! I can't recommend it enough.

The atmosphere is haunting and serene at the same time. After about an hour in the game, I just want to continue getting lost in Mirrormoon's universe.
