Mysterious Space was originally created for the 2014 7-Day Rogue-Like competition, but has received many updates since! It features many familiar rogue-like elements - including potions, equipment, and procedurally-generated worlds - but is ultimately a side-scrolling action shooter.

0.10.3 released!

full changelog is here:

but before I summarize: there's a bug I've been experiencing on my computer, but haven't been able to reproduce anywhere else: in fullscreen mode, Mysterious Space runs SUPER-slow! unplayably slow! I've checked with a couple other people, and a couple other computers I have access to, and so far the bug SEEMS to be isolated to my computer...?? strange...

if you also have unplayably-slow framerates in fullscreen, please let me know!


* eliminated more instances where you'd start a level RIGHT ON TOP OF A MINIBOSS. because that's super uncool.
* a new enemy: Wezen Web-walker
* a new accessory: Stasis Field Generator
* a few equipment & subroutine tweaks
* some Ocean worlds are now narrow and super-deep (I thought about doing this for Lava worlds, but that was too mean :P)
* made some improvements to the internationalization/translation code, to allow for more-complex string replacements. thank you, fedprod, for suggesting this!

Galaxy of Fish - a free game I made in 7 days for Emojiam

tl;dr: I made a game in 7 days. it's called Galaxy of Fish, and it's free, and you can get it here: it uses some Mysterious Space graphics, and I'll probably turn around and use some of the graphics I made for Galaxy of Fish in Mysterious Space :P


if you like programming, and you want to make a game, I really recommend gamejams! they're a great way to force you to think small: most gamejams only go for a few days - some only go for a weekend! you HAVE to think "what can I make in just a few days? what tools/assets/etc can I use to do this as quickly as possible?" so on one hand, you're almost forced to use the tools you're most comfortable with - where you'll learn the least - but at the same time, the bizarre, additional constraints of a gamejam (they usually add conditions, like "it has to inclue squash") make you think outside the box, and create a game you probably never would have made otherwise!

Mysterious Space was born from the "make a roguelike in 7 days" competition - the 7DRL - of 2014 (it was WAY worse back then, of course; you can still download the 2014 release at I'd made a couple lame horizontal shooters before, and I'd dabbled with rogulikes, and I'd done some things with C#/MonoGame, but I'd never combined all three; I might never have created anything like Mysterious Space if not for the 7DRL!

TODAY is the last day of the Emojiam gamejam - - which challenged people to make a game based on a game design document which is written in just a couple dozen emoji! ("emojis"?) I made Galaxy of Fish. which, again, feel free to give it a try: but it's worth noting that there's not much to it :P

and there probably never will be?? I know I haven't been working on MS a lot recently, but it is a game I still really care about, and still have plans for! if I have to pick between working on Galaxy of Fish and working on Mysterious Space, Mysterious Space is the clear winner in my mind. just before the gamejam started, I put together a bunch of notes on things I want to do for the next releases of Mysterious Space: some bug fixes, of course, but also a new planet type, some tweaks to existing bosses, a new enemy, and some new equipment.

it's nearly the end of the month, however, and I'd like to keep to my end-of-the-month releases... still: I can probably at least sneak in a new piece of equipment and some bug fixes, even if I can't get a new planet type!

I'll keep you guys posted!

thanks for reading, and thanks for playing Mysterious Space! :)

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:
