Nice work, I like the design, it's very bright colors and maximalist consistently across the elements of the game. The game seems a bit too easy, its pretty quick to get through the 2 levels and there isn't much challenge, I would try adding more challenges as the game develops, with more enemies and harder jumps, or more exploration. The sprite animation are very similar, so it's hard to tell when events happen, like collecting the spray can, since the animation doesn't change much, it looks like it doesn't work for a while. It also seems like the sprite sizes have not been adjusted to match the artwork, it's seems like the player sprite is smaller than the art.
