This game is really good! You have the perfect dual purpose mechanic, and you nailed the feel. I agree with Blackthornprod, add some more levels, maybe a couple more features (bonus modes, costumes, etc.) and you could sell this on steam. I know I'd buy it!
I'm not planning on doing much more with this game right now, I'm well underway with a new project. But maybe I'll come back to it in the future, people seem to want me to put it on mobile, so I'll try to learn how to do that.
