Demo is pretty bad IMO. The nicest thing is the graphics, they're very well done, very stylish, the animations look good. The rest is just not great. Environments feel too static, not enough to interact with, the occasional box to push to climb. The character feels extremely...slow to accelerate, everything feels laggy and not good. Combat is odd, I didn't find it fun at all. Again very kinda slow and deliberate and you get ganged up on super hard right from the get go with no ease into combat or real tutorials. Weapon handling is just slow and bad, same with healing.
Props for the demo though, we need to see way more of this in future, they let you instantly know if you're going to like the game. I didn't like it, many of you might, try it out for free, see what you think.
