At first - game makes amazing first impression, well done! Music and graphics are charming. I have few gameplay objections:
- the idea with abilities is nice but levels are so "open" that most of the time best strategy is rushing with double jump, if you lose it then you are forced to use rush or something else. Otherwise double jump is always best option.
- combination of camera and player movements are bad in this small resolution screen, too fast/instant/not sticked to character, I am not sure hos to "fix it", propably would be better if camera was more static on character like in Gargoyles Quest 2 (GB/GBC). I got a bit of naussea after playing for few minutes.
- reloading level animation on falling of the screen is frustrating, you feel like you lose time while you could be trying again, take inspiration from modern platformers like Celeste, after failing you need to get going as fast as possible, 1-2 seconds of animation is enough.
