So, not a quarter bad. Oh, who am I kidding, this is awesome! Anyway, I do have an issue with the tricks; There's only like one trick animation, and it's the same as the double jump. Not really fun in my opinion. Maybe have him do multiple trick moves? Other than that, this is awesome!
What i be like when i think of the neck feature: I'm on a mission and I'm coming for your neck, boy!
EDIT: Oh, and Pointy Sonic's double jump is great with sharp turns, which is why I like the move so much. That helped me a lot in trying to see if he could beat Metal Sonic in ERZ3.
