I was really disappointed at this fan game, I thought It would be way better than this. The controls and the physics were really bad and (besides Green Hill act 1 & 2) I've never passed a level without losing one life. And only the MIDI music setting worked.
And you know the funny thing about it, they removed the download link on the website and replaced it with brief message "There Will be a new version soon -" the next day after it's delayed release. That's how BAD it was.
