The crow is a bit hard to see over the background, I think you need more contrast here. It is very frustrating to have to start all over again after falling into a pit, especially considering that some jumps are really tight and you don't have any fail safe like coyote-time (I'll let you look that up if you don't know what it is). Something you could do that would be pretty easy but fix that would be to widen the collisions boxes of the platforms so it would be slightly wider than the visual, so jumping off those would be a bit more forgiving. The jump feels good.
