very nice, could use a bit more juice and while the simple shapes made the game work; i feel like having a bit more detail for the art wud have helped give more 'pop' to the game. regardless the gameplay was pretty solid, felt pretty fair for a jam game.
also a simple quick change u cud implement is having the camera zoom and pan out with the player... the farther they are to each other the more zoomed out the camera will be. this helps give an illusion of depth to the surroundings.
