Cool game. I love the red/black color palette. Nice PS1 style visuals. Event Horizon/Alien kind of story is very well crafted.. Multiple endings is a great touch. But this is not by any means a Dungeon Crawler game. This is a horror game with gridbased controls. There's no combat, no inventory, no level progression, no automap. The game level is very small.
If this wasn't a genre specific game jam, i would give this game a higher rating. This is not what i perceive as a dungeon crawler. Besides all that, i love your work and i think it's a very solid game. Nicely done!
