Super nice! Some feedback I can give is that having the camera fixed to the player's exact position can be a little nauseating, especially with how quick the acceleration is, so it'd be good to have a dedicated camera follow function to make it a bit smoother. And, of course, things like coyote time, variable jump height, etc. would be nice additions, but I'm sure you knew that. Anyway, I really liked the little story elements and the player character is super cute(giving them a name goes a long way, and was really smart), so good job!
