WASD to move and Arrow keys to kick. Press N to change maps. Press R If you or the human is stuck. Change the hit force to make yourself more powerful or weaker. Space to change what the small human looks like, and Z to change what the big human looks like, this will be an option after the first heart and star (if that even happens).
Credit to miclack for the original game, all I did to change it is change the soccer (foot) ball into a small hUmAn. And for every heart and star I will add another map and human.
