Interesting concept! The art is what drew me in and, aside from the flying enemies (which, on my opinion, don't match the art style of the rest of the assets that much), looks good, along with the animation. The gameplay is easy to understand, but the lack of sound (both music and SFX for things like the shop and the little ghosts that lift you) is a small letdown. Shame it's short, but making a 2D platformer is never easy, so...
The only part I actually disliked was the way the enemies spawn - since they already spawn chasing me, the game drifts between moments of waiting (because you need the enemies to use them as platforms) and being sandwiched by 4 enemies at once (the goblin-thing always lands on my head, for example). I mean, since you can't die, it never really gets annoying, but it might if you make a full game with multiple levels. I'd suggest working on that.
