It is really impressive that this game is made without a game engine. Great Job!
In my personal opinion, it would be so much better if we had just a little more control over Mouse’s jumps. Sometimes, the gaps between blocks can be just wide enough that the jump feels awkward.
Ran into a bug where the game respawned me right on top of nothing, in a way that I was doomed to just take damage again.
Cute game.
