I thought it's very good. I'm on chapter 6 now. My only complaint is the framerate.
As for enemies that are phasing/avoiding, special moves hit them better than standard ones (some attacks cannot be avoided if perfectly executed). Or just have Cheese as a Chao, to increase your luck (also increases the likelihood of first turn ambushes).
For regenerative enemies, beat enemies evenly, then use Robotnik's special attack that hits every enemy (did I say Robotnik?), or some other character's area attack.
Enemies give fewer xp when you reach a particular level. It makes sense, really. No matter how much you kill ants, you won't get to level 100 for it (unless its a giant boss ant).
There's a complaint that the conversation tree have no bearing with the story. I am not quite sure with that. In my experience, I am usually friendly to my remarks to Amy (you can choose to be bad, too). Later in the game, Amy asked Sonic why he's being nice to her.
Maybe the conversation trees have no major impact, only subtle ones. But, I can't be so sure until I played through the game -- and finish it all over again using different paths (yikes).
