I really like the art style of this game. Super solid and nice retro feel. I also like the little tutorial messages you've sprinkled throughout the level in the background. That's a really cohesive way to implement them. I suck at platformers so I didn't get very far but the controls seemed solid. No crazy slipping and sliding like you get in some platformer games. I didn't hear any audio? That would be a nice touch to add. Other than that, nice work!
