First comment!
The demo is QUITE long, including the tutorial and first main mission. I streamed for approximately 4 hours and didn't finish the first mission. That's not a complaint; the dungeons are large and you have to explore EVERYTHING. I died several times, but that's not a game over, which is helpful. The enemies can be BRUTAL.
I was able to move back and forth from the game to my other screen (2 screen setup) and the mouse moved between them comfortably and the game didn't minimize when I clicked on the other screen. WOOHOO (a lot of games do that, c'est la vie)
Controls are easy enough to use, and controller is supported. Yay! Each level is a bit of a grind, but once you get used to the "go in, fight, return, fight more, upgrade" style, it gets easier.
Solid graphics, fun music.
