Some of the questions were fun. I would just add more. Like with some scripted events when certain questions are asked. Also, I would definitely change from the default sky box. It kinda took me out of the game a bit not going to lie. Anyways, I make it sound like I didn't enjoy your game. I did enjoy it, just wanted to point out some things I thought. I had fun playing and it was short. My favorite type of game jam game.

very interesting take on the theme! I loved the "horror" questions , I didn't like that the earth was flat because i was on floor 19 :(. Enjoyable, I agree with Ethan Cuka on the yes/no system and the horror buildup

Interesting use of the theme! The ability to actually say no and skip the timer would be nice. I like the idea of a game where the environment around you is built by implication based on answering these leading yes/no questions. I think you could improve it by building the horror atmosphere over time, like starting with fairly straightforward questions and slowly working in the weirder ones. 

not bad, kinda creepy
