Really nice atmosphere you got here! You're right, the procedural generation was pretty similar to the one in our game haha ^^^
I like the simplicity of the creepy dude, personally I find shadows much scarier than monsters. The maze is quite big, not sure how you did to optimize the framerate, I had problems with that at some point :D
Managed to find the badge and the elevator! Can't help but try to guess which tech and algorithm you used as it was a similar idea!
Great job!
