It's simple, yet hard, move with arrow keys, you're supposed to touch the blue or yellow cubes, blue one's give 1 point while yellow one's give you 2, avoid cars, they can oof you, also, a special black car comes every now and then, to avoid it try crashing it into another cube.
Yes, it's bad, I know, but it's my first game, so can you really blame me? Also, yes, this is the game that inspired me to make "A Cube's Life" (Which you should go play if you haven't)
