Yeah I picked it up, probably not what I was expecting but it's not bad at all. I've played a couple of hours and as said above it's a psychological puzzler. It doesn't give you many pointers as to what you're supposed to do and no combat training, it just lets you get on with it.
Edit: Played some more and the pace picks up a bit and the combat is pretty fun.
Also for anyone that doesn't know that has Permadeath ie die too much and it's game over!
