Very ambitious for a jam game! Building the rocket reminded me of the board game Galaxy Trucker (check it out if it wasn't already an inspiration)! I am not a kerbal space program veteran so I have no clue how to make a good rocket. All mine seemed to plunge straight into the ground. I did also get a bug where if I used the map screen, it wouldn't go back to the rocket build screen after it had crashed. Anyway, I had fun with this, nice entry :)
