It looks and sounds very fun but suffers from some classic platformer problems.
I have no idea if I'm going to land on ground, on an enemy that kills me or in a pit which kills me. Some work with the camera would make it much more fun and playable!
I couldn't get very far because of this, but would have loved to play more of the content.
I think you have a nice art style and nice sound effects. The music gave me some good old mario kart vibes :D
