I really enjoyed the pace, I've been playing several games and one thing people struggle with is game pace (usually too slow), yours is great.
The game is a little frustrating tho, because sometimes you just fall into spikes from simply changing the room and not knowing theres like 2 milimeters of floor before a spike pit, and you fall and lose 2 lives in the same second.
But definitely a solid submission and a game with lot of potential if properly polished. Also another godot fellow, which I always enjoy.
