Hey, a lot of stuff to say, tutorial is not the best as just after i learn how to jump you immediately throwing me into 1 block wide challenge with not even same jump sizes, this start of the game should stretch for 10-15 jumps before even first possible death for player. movement in the air is to uncontrollable and coyote time is needed. i would recommend to give MORE freedom to the player) at least at the start. but overall good game!
Inviting you to play my game) maybe there is something interesting for you there <3
