I gave this game a play and I found the controls to be a little tricky to work with but overall it's a good game with a creepy and mysterious vibe to it.
The system of using numbered buttons to select an item in your inventory as well as using the mouse button rather than say f to use your flashlight or some other button on the keyboard to take some getting use to. It didn't completely ruin the experience by any means though it is a high quality game and that is just my personal thoughts, I'm sure lots of people are just fine with those controls.
