Okay, this is a bit of a plug for the game since I'm now working for the company that made the game, but they finished it before I started working for them and it actually is a good game. It's a neat mix of a puzzle game with a horror theme.
I'm currently up to level 12 (out of 30) and the puzzles are already getting quite tough, in a good way. The artistic style is also very cool in the game and the bosses add a nice variety to the gameplay. My biggest grips is the lack of a tutorial (although the controls are quite simple, so it doesn't really need one) and the context sensitive controls can cause me to turn off a lamp when I wanted to use my flashlight (but being more careful to pay attention to the action icon is helping with this problem).
I should wait until I finish the game before giving an actual review of the game, but my initial impressions are the game is a 4 out of 5, and considering it's only $8, it's definately worth the download.
