Gave it a try! I liked the atmosphere and the monster designs are cool. The battles also where quite fun, not too hard, but you had to manage resources. What I was wondering is if something would happen if the hatred level got full, which it never did for me, because that name surely sounds like something like a pure rage or whatever should happen!
The critique I'd have is that everything looks a little too much alike. Too little variation in tiles to make places feel unique enough to map everything out in your head. It also felt somewhat linear, but that might be me missing things? Also if it is linear, the first point isn't as much of an issue, if it's not, it's becoming more of an issue to remember where something was.
I didn't finish the demo and stopped somewhere in the sewers (didn't have time to finish), but played for like 40min.
All in all, good job, curious how this will evolve!
