I like the simple aesthetic and the concept of the game. The controls feel a bit slippery at first in that you tend to go too fast or slow with not enough power to correct yourself but after playing for a bit more I got used to it. I'd suggest the health and jump indicators be more centered or even part of the player sprite itself (think of how Madeline's hair in Celeste represents if she has a dash or not) because sometimes it would be hard to track how much health or how many jumps I had left.
