Significant enough for an update push

I know a few people are looking for bugs and finding a bunch. I was looking for them, too. I found a whole lot and patched them. And, I fixed a bunch of abilities along the way that I thought were working and very much were not. Twin was definitely the worst offender.

Another big improvement is the combat algorithm. It is way more efficient now than it was.

Also, those abilities like Darkness can be unlocked.
