A bit repetitive, and the premise has been done before. The pixel art was well done, and the overall feel is certainly suspenseful and creepy. A nicely crafted game, and worth a play through or two. It would've been interesting to read the notes, or have some additional control over the character; slowly meandering left to right does get a bit boring. A simple run button would've been a nice addition aswell - maybe using it would deplete your stamina twice as fast?
Interesting concept, just a bit bland.
