Fun game as a whole, certainly looks like there'll be a lot more in the future. That said, it does look like the talents (or whatever that last tab is called) needs a bit of work. It keeps getting clogged up with not only useless stuff, like blade skills on a mage, but stuff that I literally don't meet the pre-requisites for. Not being able to select any more for the rest of that run because all you've got for options are things you can't select just doesn't make sense imho.
I'm looking forward to seeing what the caster paths offer. Looks like those aren't in the demo right now, or at least aren't completed. Still, it was fun so far as I was able to find out.
