The art style and audio were incredibly well done, and this certainly feels like the most polished entry I've tried so far.
My only comment is that the controls felt a little clunky - I eventually got used to them but I found myself having to spent a lot of time "lining up" my next leap, rather than it flowing naturally (it could just be that I'm bad at the game though!)
EDIT: The little magnet guy was incredibly cute btw!
