I'm about halfway(?) through the game, and I'm astounded at how little buzz it has gotten outside of adventure game circles. The best way I can describe it is "The Crow plus Catwoman plus Chronic Depression plus David Lynch". It's ridiculously engrossing, despite some instances of cheesy dialogue and "I clearly got my friends to record their lines over Skype, and I will make no attempt to hide this". The only things I don't much care for are the control scheme and the jittery animation.
If you liked Walking Dead, but wanted more actual puzzles, play this game. It's not as emotionally devastating (so far), but beyond the crazy violence, it's a surprisingly sincere look at depression and suicide. It feels like you get to impact the story to some extent also, but I can't tell for sure yet.
Edit: I feel like I shouldthis, as it's directly up his alley.
