Really nice game feel, can definitely feel the celeste inspiration. The visuals are very clean and minimalist in a good way, lighting is clear, nothing is confusing and the palette is cohesive. Level design was also pretty good, it slowly taught the purpose of various platforms and interactables. I think maybe a slightly higher ratio of challenges to repeated stretches might be good, but that's subjective. The combat mechanic is interesting - there's definitely potential to add ways to interact with your arrows in a platforming context instead of having them solely be an enemy combat mechanic. Bouncing, sticking them to walls as platforms, maybe even some sort of recoil in midair...lots of possibility!
