The writing is good. The arts is nice. Although I understand that you used premade assets, the effects you applied on them make them good imo.
However, the thing is that the gameplay controls feel really bad to me. It kinda baffles me how the character seems to stick himself onto walls whenever he jumps, it feels pretty bad. The movement in general is also not that satisfying, but it's not as big an issue as the "wall-sticking".
