Got the best ending within 7.5 hrs on my first try. Awesome little experience. My only real gripes would be technical: really dopey and funny enemy animations (which completely ruined any semblance of intimidation they could have provided), overall funnily bad facial animations, and random performance issues (specially while using the flashlight) I paid 8 bucks for it so def got my money's worth, i'd say it's worth a good $20! Get this game if you like a good story, good graphics, engaging dialogue, and decision making.
I have it on steam and it was fully worth the $5 I paid for. 2 playthroughs so far, each 40+hrs. Truly haunting environments, awesome combat system (very 'meaty'), cool progression system. Can get a bit repetitive, but never too bad (just don't stress over missing that one dang missing piece of loot...)
I played maybe 3 hours of this, so I'm not getting the 'full' experience. While I appreciate the effort that went into the backstory, lore, graphics, sound design and all, I find that these types of games (dungeon crawlers) just don't click with me past a couple of hours. I did like the atmosphere, but I found the combat and puzzles to be too annoyingly hard. A very subjective take, I guess.
