Such a polished experience. Lovely pixel art and juicy effects that complement the gameplay. You hit it out of the park with this one.
The only thing that I think should be reconsidered is taking damage while charging the yoyo. From my short experience, it never feels like there's enough space to do it safely. Maybe there's a different way of making positioning important, or maybe it's just making the level a bit bigger! Or maybe be immune to ranged attacks at least?
In any case, nice job!
