Note: If you can't click on the build button in-flight, you can use the game menu (press enter) > BUILD


Things I had no time to implement (SPOILERS!): 

  • Fuel is not spent, you can fly without any tanks
  • The Picraken will catch you if you fly too far
  • You can place parts disconnected and overlap (tho it's unrealistic it's kind of cool that it gives more artistic freedom :D)
  • No part rotation in build mode
  • You can spin up infinitely fast, and everything will be fine
  • No map or zoom out view

Source (only code, cart coming soon):



  • Crash velocity is now calculated correctly
  • The craft gets pushed now when a part crashes into the planet

the game crashed, its saying out of memory

I know, it happens often. Not sure what exactly causes it. Probably won't fix it. If you are interested, the source is here

i think its because i pushed it to the absolute limit

I thing I crashed it, it sais "out of memory."

please make updates.


Nice job! this is a great simulation. Some ideas for the future: 

1) decouplers

2) angular friction

3) zoom in - out

4) atmosphere

these tips might be too hard, but I think it would be AWESOME if you manage to do it!

oh and another one: Map screen

I won't be updating it. But the source is available so you, or anyone else, can add features yourself.

Thank you for informing me about this

hhow to fly?


what are the controls?


earth is flat!


Yes, you right =)

oh man, I love this! the pico 8 is so powerful...


Couldn't get it to launch....



Awesome game! Could you just please make a downloadable version? Thanks!

Uhhh... How do you progress and reach other planets. I just keep flying out of the screen and it glitches out. how do you win.

good so far and has some serious potential. some more parts and a big map would be nice, maybe even some more planets. I cant wait to see further updates!

I might fix some bugs and clean up the code, but I don't think I will work on it much more unfortunately. I just have too many other projects to work on. However the source is out there and anyone could add to it.

i broke the game

Congrats! :D

not realy i couldn't restart because the clicker what out and the ship wont crash

You can press enter and go to the build mode from the menu

oh i dident know that thanks
