An interesting core mechanic packed with a whole lot of style! The trails, background effects, the fluid pixel animations — this is just so pleasing and satisfying to play, with lots of room for expansion and future development if that's something you're interested in. New enemy types, level variants, and different ways to use the two dimensions could elevate this from a fun, short arcade experience to a deeply engaging action game. As it stands, though, it's already dripping with polish and was a delightful surprise!
