I loved the art style of this game!!!! It gave me some really nostalgic Limbo vibes which was really nice to see. This game was really polished and fun to play, I ended up playing it for a good while!
I'd say the only issue I had with it, is sometimes the collision detection wouldn't work all the time, for example sometimes it would let me double jump and also sometimes the enemies hitboxes would hit me when it seemed I completely cleared them.
Other than those minor issues, really good job!
