I love this so much, it oozes 90s character at the start, with that song almost out of Ridge Racer or something combined with the ending of each level spiraling up to show the whole level. Crazy Bob was kinda creepy, even from the start; I was constantly wondering when something was going to happen, haunted ROM style. I loved the voice acting, again felt like it was straight out of the 90s. I wish the game was a little easier to control, but in a way it emulated the poor, non-standard controls from that era too.
I thought you did really well making the maze itself turn creepy, particularly in the first level where things started getting creepy, and detuning all the audio helped a lot too. You did well to make the game unnerving without being obvious about what was going to happen next. Overall, I think you hit the creepy feeling you were going for perfectly :).
