Just a minor quip, but when Knuckles spin-dashes, the camera doesn't lag behind him like it normally should. And if the other two are spin-dashing, the camera spazzes kinda when those two go off. This hack is still amazing, regardless. One little suggestion is maybe tewaking the AI so, for example, the order is Sonic - Tails - Knuckles, that Sonic jumps, the Tails jumps, then Knuckles jumps AFTER Tails, rather than WITH Tails. Maybe increase partner 1's reaction time somewhat so it comes between the player and what it normally is?
