Theme: Not really a horror game, but a good maze crawler
Fun: Wasn't a fan of the cryptic story, but the maze was alright. Liked how it became more and more crooked over time. The fighting mechanic felt more gimmicky, as the enemies weren't much of a threat for the entire game. Maybe make more use of the flashlight/lightbeam detection you had - like, you can see only the parts of the maze you lit, and have it like a flashlight.
Game Design: Good work, liked the maze crawl. Can't say about the poem, as it's not to my taste.
