Great game! 1 recommendation though... i feel like it would be better if the movements were smoother and the character still moved a little after you release the key, like momentum.

forgot to put this in my last post, but also you don't lose enough when you die because if I get more than six coins before I die, I'm still gaining money.

this is a BOSS platforming game!!! oh yeah! but by the way, you can't fall through a one-block space unless there is a wall, so on the first level, at the top there is a one-block space, i don't know if it's just for decoration or what, but it does nothing. Amazing game though!
