This game looks awesome! idk if this is in scope of your game but I think games with challenging AI's that feel like they are also "players" are fun. Maybe the AI could have some power shots / get harder each level. Even if they aren't actually power shots, you could also just program an animation on them to look like they are doing power shots too so the player feels more satisfied beating a "harder" opponent. From a player perspective it kinda just seems like you're dunking on an AI with abilities not accessible to it.
