Very pretty, cool music. The butterflies are sweet.
The game feel was quite off though, there wasn't any "coyote time" to jump after you reach an edge like there is in other games. The jump arc felt off, maybe too low but floaty at the same time? The hurtbox of the player was too large compared to enemies. Often I was blocked by blocks touching my head that I did not expect to block me. The levels often had blocks placed in a frustrating way, just barely too high to reach from the ground. The way the enemies block you after colliding felt strange and inconsistent.
