ah yes bean thats a rocket
'e' to mine rocks on the moon, arrowkeys to move
mine rocks by going on the moon, return safely (going over 2 y velocity will make you go boom and you will lose 1 moon rock), and go to the refueling station to.. well.. refuel, and sell the moon rocks in exchange for a bigger rocket and more fuel space.
this game is kinda the first one with some great effort
i hope you enjoy bean rocket! :)
note: make code efficient and not just if's
