This is one of the best character mods I've used. They all control very well at the speed that they go. I do have a couple nitpicks though. For one, I think the old wall dash before MC Tails was released is better and much more flexible than the current wall dash were it's more like a wall jump and always sends you to the opposite direction that the wall is facing. Switching between Sonic and Tails sometimes causes sudden speed increases when already at high speeds, which would be a bigger problem if we couldn't curl after slipping off a platform, but we can so its not too harmful. Overall though, all the moves are actually useful, and makes almost every level in the base game, and contests much more dynamic as the way you view the level changes drastically. Max/10, would Control again.
Also, that JonTron voice clip is a nice Easter egg, though I don't know how I triggered it, or how to trigger it again. All I know is that I thought Sonic was mad at me for defeating Metal too fast.
