I am working on non-uniform parts (it wont rotate along with the main chasis) so that will tremendously help with people who would want to try beating this game, also the rocket is kinda bugged a bit with how they actually propel the main chasis (rotation stuff haha i hate it)

other than that you shouldnt be putting wheels close together, and you can just put the parts anywhere you like (as long as they dont overlap with the stage lol), idk if theres any connection bugs as of right now pinjoints in godot right now is very simple to use but stupidly hard to recalibrate. so it might have just been a weird placement you did,

i dont expect anyone to beat this version right now but if you managed to get at least 5 out of all the stars pickup that means you did great!
