Hmmm, you game seems to be somewhere between Super Meat Boy and Celeste. Which may be a good idea, but the controls are too unprecise: Low air control and the wall jump is the major threat instead of a power in the first levels (as it can get you stuck to walls without the intention of doing it).
I played until the end of level 4 where you have to do this big jump over the spikes at the end. That's just frustrating, so I stopped playing here. Until then, I enjoyed the game.
Hope this feedback helps you somewhat ✌
