October 8 release

the addition of Endless Mode has lived up to my expectations as a game-breaking feature :P

and I don't mean crashes! which have hopefully all been fixed as of about 5-6 days ago >_>

I mean game-breaking in the sense of accessory effects being stretched beyond the limits of sanity, and areas of Folded Space so long they make a grown person cry. of boredom. fixes some of these most-glaring issues; I'm sure it won't be the last such patch!

one thing to note, before getting into these fixes: many of the ship part fixes are applied at the time that the ship part is actually generated by the game... so if you've got an Endless Mode game in-progress, your already-generated ship parts may still have negative cooldown times... (similarly, if you've saved in the middle of a planet with an obelisk, it will still have a painfully-long region of folded space; only newly-generated planets will be affected.)

here's the full changelog; thanks for reading, and thanks for playing Mysterious Space :)


* Vampire Shields were having > 100% chances of granting bonus shields. This
has been fixed. (Other tweaks to Vampire Shields are listed below.)
* The following accessories can no longer have negative cooldown periods; they
are now capped to some minimum, usually 10 seconds: Last Resort, Deck of Many
Things, Phase Shield, Stream Interrupt, Alien Teleporter. (Other tweaks to
these accessories are listed below.)
* Similar to above: Hull Repair bots can no longer repair faster than 1 point
per second.
* Engine Booster speed boost can no longer exceed +100%.
* You can no longer see the name of an unidentified Deck of Many Things.

Folded Space

* The length of Folded Space no longer increases linearly as you progress. (No
more 5-minute+ Folded Space segments in Endless Mode!)
* Early instances of Folded Space contain more simultaneous background stars;
the number of background stars no longer increases linearly...
* The amount of debris found in folded space still increases linearly, and the
rate at which it increases has itself been increased! (Look forward to
shorter, more-intense sections of folded space near the end game of
normal/story mode, and throughout Endless Mode.)


* The maximum bonus shield a Vampire Shield can give has been increased from 5
to 15.
* Vampire Shields can now grant bonus points for enemy kills; this has no cap,
but does not increase linearly.
* The maximum effect from stacked blessings on Last Resort has been increased.
* Late-game Last Resorts deal less damage to you, and eventually start coming
with increasingly-powerful Blessings.
* High-level Lightning Generators may now have additional strikes or chains.
* A high-level Deck of Many Things may now cause multiple good things to happen
each time it triggers (but never multiple bad things).

October 2 bugfix release + a new subroutine

there was a nasty bug involving Endless Mode games, where upon loading an Endless Mode game, the game would probably crash on a later level. this had to do with the minimap... the game was mistakenly giving new planets the same ID as a previous one, causing it to re-use an old minimap... which in turn would crash things, since the minimaps were probably different sizes.

I tried to find a fix to preserve old Endless Mode saves, but couldn't quite figure it out. sorry about that :|

some good news: I happened to have started work on new content, so that's getting wrapped up in this update as well. here's the full changelog:


* Fixed a bug where loading an Endless save game would probably result in a
crash when visiting a later planet. (It's weird. Don't ask.)


* New subroutine: Black Mushroom.


* Trail Guns can no longer have EMP bullets.


* The movement speed penalty and push resistance bonus of Heavy Armors
has been reduced from 20% to 15%.


* The Ophiuchustians no longer have more than one star chart for sale at a
time. Because finding a shop half-full of star charts is REAL ANNOYING.
* Ship parts sold in shops now have a greater chance of being "blessed".

About This Game

Originally made for 7DRL 2014, Mysterious Space tasks you with delving deep into the ZZ-Omega sector to recover an important piece of information, and to return with that information in one piece.

To get there, you'll have to stop at planets along the way to find much-needed fuel.

Arm yourself with procedurally-generated weapons, armors, and shields to defeat the enemies that stand in your way.


  • Local co-op, up to five players
  • Procedurally-generated planets, including forest worlds, desert worlds, ice worlds, lava worlds, and others
  • "Alien Artifacts" and "Advanced Technology", analogous to the potions and scrolls of rogue-likes: does the Red Alien Artifact repair armor this game? Or will it scramble your sensors for 10 seconds?
  • Unlockable ships and ship upgrades
  • Procedurally-generated weapons, shields, armor, and accessories to equip yourself with
  • Various enemies and mini-bosses, with distinct movement patterns/AI
  • "Secret logs" that reveal the lore of the world (galaxy? universe?)
  • Supports XBox-compatible gamepads (you'll need them for co-op!)

Mysterious Space's soundtrack - by DDRKirby(ISQ) - is available for listening and purchasing at bandcamp:

I've played the best part of an hour and thought I would leave my initial impressions.

Great music. I love it. It's a bit of a mix of the old school chiptune vibe with a twist of the contemporary.

It doesn't have the option to rebind keys but the default is a fairly common WASD setup. The native xbox controller support works like a charm and it makes use of the analogue sticks with progressive flight controls(push it a little to fly slowly, push it a lot to fly fast) so I would say a controller is the way forward.

If you've played a roguelike before you'll be familiar with the ?? pick ups. Instead of potions and scrolls you get alien artifacts and alien technology. They come in usual buff and debuff flavours but are all themed to fit into the world. Blindness/confusion potion becomes a Sensor Disrupting artifact etc. After you've use a ?? mystery pick up once, it's identified and the next time you get it, you'll know when to use it or if you just want to jettison it right away.

There's no XP system but there is equipment to loot, which is all procedurally generated a la Borderlands, which is great. I found a couple of different shields, one had a higher total capacity but slower regeneration, a low capacity shield with very fast regen and I found a few ship accessories. One boosted fire rate at the cost of shield regen and the other allowed me to regenerate armour.

The other way your ship progresses is through upgrade parts. They are like skill points you can find and then you can choose to add another weapon slot, the only gun I found on my run boosted my front fire rate a fair bit but also had a rear fire which was great or you can increase your hull/cargo capacity and thrusters.

The "overworld" isn't too dissimilar to the FTL star chart. You move from left to right and you can branch off now and then taking a longer route to the goal to go hunting for loot and upgrades. While you are in the overworld aka space you can identify your mystery parts and potions.. I mean artifacts and you use your upgrade parts. The UI is simple but effective and very easy to work with.

When you are done messing around in space you pick the planet on the star map and get down to business. I think I seen 4 different kinds of planet. Desolate, Ice, Forest and Water. There are some cool environmental effects like a Sandstorm type deal that blows in from the left or right and slows or speeds you up depending on which direction you are going. On the Ice planet I noticed a nice little fogging/frosting effect at the edges of the screen, while on the jungle planet I think I was attacked by some sort of space locusts.

It's really not as punishing as most games with roguelike elements. I was reduced to zero Hull(that's after 0 shield and 0 armour) a few times and was allowed to carry on but my equipment degraded. Shields regenerated at half speed, my gun lost x amount of power. So while you pay a bit of a price, there is enough loot that at least a placeholder item wont be far away. You can save and quit anytime, too. That's always good.

Anyway, this is just supposed to be a bit of a rambling first impression seeing as there were no reviews at all when I got it. So far I really like it. I should add that the little writing I got to experience was well done.

This feels like a game you might have found on a CD full of shareware in the mid 90's. Or maybe downloaded off of Jumbo Games or the like. It's the kind of game you sit down to play for an hour. Then come back the next day and play again. It's got that subtle addictive quality. It's a very good blend of easy, approachable, and challenging. Almost feels like an obscure game Apogee might have made back in the day. Every time I've played it I've experienced new enemies, upgrades, and obstacles.

I love that I can collect items to unlock new ships, and these ships recieve completely different effects from the artifact/potion pickups. Each ship is a totally different game.

My only complaint is that in the very late levels I keep dying from being rammed, despite whatever collision damage reducing modifiers I've equipped. Even in the speediest ship, which I transitioned to by a chance powerup, later levels feature so many spawning enemies intent on ramming you that it presents a huge challenge. But of course, this a rogue-like, and daunting challenge is to be expected.

Still, I wish there was a cloaking device with a timed cooldown cycle that when activated would prevent me from picking up anything or firing, but would hide me from the enemies. This would allow me to better tip toe around the later levels and cloak & heal when resistance gets too tough. Ballancing this, most upgrades are only found by shooting enemies, and some fuel has to be obtained from mini boss battles. For all I know this upgrade is already in the game and I haven't found it yet, that's how much neat upgrade loot is in this game.

If you like the idea of an action rogue-like with a sort of Fort Apokalypse meets Defender vibe, definitely check this out.

This is a fun little action-roguelike. It's great for a quick run, but also has that addictive "one more try" factor. There's good variety in the environments and random loot. Seems well balanced. The music is great, but a few more tracks would be nice. A controller is definitely the best way to play this. Thumbs up!

This is worth far more than the $5 I spent on it. The planetary action reminds me strongly of Solar Jetman (NES), but the worlds seem to be made from scratch each time, so each one is always a new experience on dropping out of orbit. There are several different sorts of worlds, each with its own hazards that only get worse as one progresses along the path to solving the mystery. A wealth of powerups (and power-downs, some pretty severe) make each playthrough a real adventure.

It's basically a sometimes very tough free-scrolling shmup with roguelike elements. Some acquisitions are "Collection" items that affect all future playthroughs. The music is pretty sweet, and the sound effects are distinctive for each enemy and its fire.

(This bit here contained a complaint about the "Teleporting Eyeball" enemy being hard to notice and showing up too close to the player's ship to avoid, sometimes, but the developer has addressed both those concerns on this first day of 2016, and made a previously somewhat cumbersome equipment system a bunch easier to use, to boot.)

tl;dr: GET THIS if you like solidly-done blasty gameplay and getting cool (and uncool) items, with a nice bit of story on the side, and lovely music all around.

Looks like a good spacey, pixel-arty 2d scrolling shooter. Kinda has the feel of an updated Asteroids and/or Defender. But with better control and procedurally generated gameplay elements. Overall map, level map layout and visual, and items names are generated. Item effects and enemies are randomly selected. Visual issues with the game are now gone (headache mode is gone, thanks Ben!).

• Pyoo pyoo.
• Procedurally generated maps.
• Random loot.
• o y am i ded again.
• Very responsive developer. I reported three issues. Three issues were fixed. Quickly even. Got a personal response, too. And this, while other features and fixes are getting pushed out too.

• ???

Fantastic roguelite hybrid space shooter. Usual P+C;
+Easy to pick up, simple and relaxing gameplay
+Good variety in ships, enemies, upgrades, items and worlds
+Good difficulty curve, hard to finish but you rarely feel like a game is already busted 10 minutes in
+Excellent music, different track for each world that sets the tone nicely
~Game doesn't last as long as you wish it would. Not necessarily a design failure, personally roguelikes that ask me to play for 50 hours to figure it out and then 50 more to finish it just get dull.
-Graphics style may turn off some; I find it appealingly retro
-Game could use a lighting or shading engine (see Terraria for a simple example)

Lots of potential here. And the dev seems like a really nice guy who really cares about this project.

This game has a lot of cool ideas, but can be really really frustrating. It's easy to miss things that happen onscreen because things are so tiny.
At first I got really aggrevated by the force fields and couldn't tell why I was losing damange. The graphics are really subpar and there are much better rogue likes with similar themes. I don't really feel immersed in the game like I do with other roguelikes and this is probably because of the low budget graphics and sound.

Really liked the music. Graphics were ok ut very basic - which actually fit the music ok.

OVerall though it was just frustrating. WHen I play a roguelike I want to feel as though when I die it's my fault. With this game I felt like it was entirely up to chance. Maybe after youve found all the mystery pick ups its easier but I don't like having to die this much just to learn how to play the game.

This is a very fun roguelite/like/whatever. Your basic loop is to visit the planet, pick up the fuel and get out. It has a Defender vibe since you're going horizontally. Each level is randomly generated with plenty of challenge that ratchets up the longer you're flying around. In the Rougue-ish tradition, there are mysterious pickups that can be good or bad with buffs, debuffs and upgrades following their identification. This isn't a flashy looking thing but I just imagined the geometric shapes were Bill Cipher and it made it even more fun. Swell soundtrack too.

Enjoyable relaxing game. I have played many rogue-likes and I found this one on the easy side which is okay. This game is in the style of Defender(Atari) and Aqua Kitty. The music and atmosphere is the standout. The different planets could stand out more by having different monster sets.

For the price i recomend it.

I am looking forward to giving co-op a try.
