Nice work for a first game - I liked the idea of it being like an arcade version of Outlast. I wasn't too much of a fan of the title screen graphics and I felt the maze needed more batteries (I spent most of the time running around in the dark bumping into spikes and accidentally running through the fake walls lol).
I loved the fact you gave a little tutorial section for encountering the monsters though and that you offered different difficulty modes. I think people who don't like horror games will appreciate the 'no-monsters' mode.
