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 cameraman is fucking terrible at his job. Should fire him smhh. Anyways good job on doing the impossible tho.

Orbiting Kerbin never been that easy Very impressive work btw

hi there can you post the cart version the source dont work on pico8 thx


I ended up making this...the pico craken finder

Love it!

this is a good game i was able to make a small space shuttle 

i found a glitch where the right and left keys are inverted

(1 edit)

can you add another planet,landing legs,more part,map etc.

The game is awsome, propably my facourite space game on, minimap would be great!

Can you give source code

i achieved orbit

i achieved really fast


Will this ever be updated again? I love this thing and it would be awesome to see it expand.

Hi, can you share a file?


It'll be cool with map and more blocks

yea, minimap would be great!


how do i start the launch?

top right corner button

i found another glitch, i make a triangle spaceship and to fill it in i just put in a bunch of wings and also 2 thrusters. when i tested it out it just started going in the wrong deriction it was going west, no matter what i tried. it went into the wrong deriction at start.

i found a glitch. this glitch is where i make a nice straght (very long) spaceship and i add wings using the thin  fuel tank it started to turn very quickly, i decided to just start spinning  and i started to look like i was powering the entire spaceship. then when i also turned my boosters on a few seconds later the spaceship just exploded.

Yeah, the physics is kinda hacked together, there's a lot of weird behavior I also noticed haha. I won't be fixing it, unfortunately.

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


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
