Overall a fun game! I like the level design a lot. It was very fun. I do think some extra polish could be cool:
- make camera follow smoothly instead of locked to the player
- character movement is quite good, but coyote time and jump buffering could be added to take your character controller to the next level (okay, these are details but still)
- graphic wise, the game looks okay with nice animations, but I feel like colors are under-used. Go grab a nice color palette online and give the game more color
A very good entry overall, keep making games!
