This game is pretty fun and a great time killer.
In my opinion I think it would be better if the player could control the jumps more. For example if you needed a short jump you tap W and he does a really short jump. Ik that mechanic is already in the game, but it didn't feel sensitive enough for me. The game also felt slow it was still challenging but i think it would've been more fun if the character sped up more every time he hit a checkpoint.
All in all the game is simple and really enjoyable. Thanks for the upload
