What an amazing game!! I'm not usually a fan of the horror genre, but this wasn't overly scary so I liked it (except for the giant stomping shadow man - that was terrifying)! I played this game for about an hour and still had more to explore and figure out - just shows how much content you were able to put in here. These kind of walking puzzles also aren't usually a strong point for me, and even though I took lots of notes, I wasn't able to beat the game.
I'm astounded at how much content you managed to include and how well you incorporated the limitations (including "something follows you")! Also, in an hour of playing the game I didn't find a single noticeable bug! Great job.
