This would be so amusing if you were stoned.
Hell, this is fun even if you aren't. I got around 66k distance going with Tails. A few notes:
1) Whenever you select "Shoot again" on a course, it adds to your ring count.
2) You should have two or three music tracks, with three buttons - so the user can play whatever kind of music they want. After a while, the music got old, though it was cool to have the game's title in the music. :D
4) I went in to beat the boss, and it took me a little bit to figure out how to beat him. I had over 2k rings at the time, so dying wasn't going to be a problem. :D
