The HTML version is working a treat! Played to the end, wonderful little game. The costume changing mechanic is fun and makes intuitive sense. The level design had some though put into it and made for a nice little challenge without being frustrating. And a nice story arc conclusion at the end with a heart warming message. Love it, really impressive, especially since you made all the assets and music yourself. Great work!
