Haha, glad you were able to beat the Chimera. I was about to think about nerfing the Chimera (and I still might a little, just because you're stuck until you beat it and that can be frustrating). I'll at least lower the time needed for the Ranger so you don't have to wait 4 minutes blocking and dodging if you can't beat it.
The thing I had forgotten was to re-allocate the skill points (after being spliced they all got removed). As soon as I had done that it was real easy to defeat the Chimera. So I'm not so sure if you should make it easier.
By the way, what happens when you press "New Game"? Will a new slot open up or will all the previously stored games be replaced empty slots? I'm afraid to press the button in fear of losing the stored games.
