There is a demo and IMO, if you like turn based blobber/crawler at all, I'd suggest trying it.
The demo "shell" is rough and there's a (~10 secs for me on SSD) preload. Game itself is in better shape than the "shell." I'm impressed as heck - this game is easier to hop into and more immediately attractive and interesting than most similar games I've tried, and I've been trying/buying many lately.
Solid overall production values, graphics, combat system is engaging/tactical, map + lighting system and how they interact is cool, UI is clear and easy to use, combat "view" and transition is cool. Solid controls (I'm using controller but it asked, a nice touch in an indie).
The game has (to me an unintentionally smart assed) tutorial system whereby you get a popup explaining something AFTER you have just screwed it up, and then you're like OH, that makes sense. Maybe you only see the tutorials if you're bad like me - wouldn't surprise me in this game.
There is some story (probably related to what @lackblogger; was mentioning, which is at least different from hey, a tower just popped up next to the inn, why don't you go plunder it?) but I didn't pay much attention since I wanted to hop in and see how it played.
