This is very well done, but gosh I'm bad at it lol. Based off my own skill level, I would have liked some more built in check points. Just a raised block or something for Eugene to run between while I figure out the next segment. Some parts have Eugene fall pretty far back if you mess up.
That being said, it's a clever use of the theme. Eugene has some funny lines, the art and music is great, and the controls over the fairy are pretty smooth.
Great work!
