First of all, I like your art style for this game; it reminds me of a game developer, Blackthornprod. It was a good idea in placing enemies and pickups from the floating boxes, makes for a nice risk-reward feature. If you decide taking this project further, I would suggest creating levels set by the number of red macarons, you need to take out, while changing the landscape and platforms for the player to navigate around in. Overall, nice job on your game project!
