So I pledged and played the demo for a little while, which I liked a lot!
A few things I noticed:
please implement "Space bar" to close all open windows (Character, Items, Skills...). Thanks to years of Diablo, this one is hardwired in my brain and I can't unlearn it ;)
it's a little overwhelming at first, there are lots of items, skills and stuff thrown at me in the first minutes. Introduce these things more gradually. For example, resistances don't come into play until a few hours into the game in D2. Also introduce rares, uniques etc. more slowly. It's too much too quickly now.
the demo is too easy and levelling up is too quick, as well. we don't need a reward every 2 minutes.
performance is subpar, which is unfortunately often the case with Unity games. (I played on Linux)
enemies don't have "dying" sounds yet?
Overall it's very promising, so good job so far!
