Screenshots look pretty good. Downloading the demo now.
Okay played the demo, here's my small review:
The menu was a bit weird, because I don't know if it was bug or intentional, but the cursor got duplicated several times as I was moving it on the screen.
The level design was pretty good, and there's some nice small details in the environment (like that girl hiding from the spider in the cell of some sort). Lighting was OK, nothing special, but not bad. The level was a bit too straight forward (putkijuoksu).
There were lots of different enemies, which I like but their visual quality varied pretty much. I think the cyclops with the club was the best. The positioning of the big spider was pretty bad though, because it killed me before I got myself into the room.
Music in the level was a bit repetitive, just the heart beat or whatever it was. The menu music was simple, but it worked.
Overall it was an average game. I didn't get any "WOW" experiences, but I still liked playing the game.
So, from 1-10, I'd give this game a 6.5/10
