Your game looks pretty neat and I like your style, but unfortunately I had too many issues to be able to play it :(
I'd highly recommend adding WASD bindings in addition to the arrow keys. My keyboard doesn't have arrow keys which I suppose is a personal problem but also an accessibility issue. The viewport also didn't fit on my display (1080p) which cut off a lot of the playable area.
From what I could tell, the movement is very smooth. That's super important in a game like this, and I'm a sucker for precision platformers. You nailed it
Fusili is precious
