Ended up with 1 speed, fuel, boost and didn't appear to be any way to buy upgrades.
Also not sure what "spamming" meant - thought I was in for Daley Thompson's Decathlon at one point, but there's not a lot of feedback about what the space bar does.
Still wound up launching about half-a-dozen times before it looked like I couldn't make any further progress.

lol yea some things should have been made clearer to the player, like how spamming the space bar will only give you some boost at takeoff. As the spawn of the stars and space junk are pseudo random it can feel a little tedious to launch again and again just for those 1-2 junks if you get a little unlucky. Oh well. Thanks for playing the game and the feedback as well :)
