This is really good and very polished. I normally hate tight platformers but I played way, way past my normal point of frustration on this one. I did finally burn out towards the end of the third level. Some more forgiving checkpoints would have gotten me to keep playing longer.
The fans are a super cute use of the assets and the stump-volcano monsters are creepy and visually effective.
I found that I was flapping the fans in the wrong direction a lot, especially while jumping where I'm trying to switch from air control in one direction to fanning in the other direction or downward. It's probably because my reflexes for this sort of thing aren't great but maybe there's something that could be done with the controls to ease that, I'm not sure.
