Fun concept! I feel like it could be fleshed out a little more mechanically, playing as a powerup feels like it should have more of a unique twist?
The platforming feels inconsistent too, I think its the lack of differentiation from foreground and background and a bit of a janky camera. Good job getting this over the finish line
(You can get clean imports on your sprites by setting filter mode to Point (no filter) and compression to none on the sprite import settings btw!)
