This game is perfectly scoped for a game jam. You found a unique mechanic and polished it to perfection. The aesthetics are clean, the audio compliments the setting well, and actual mechanics of answering questions worked flawlessly. I wasn't able to escape yet, but may give it another go with the hints when I have more time later.
Some things to point out, I didn't notice the walls closing in until the 3rd or 4th wrong answer. It needed a bit more of a visual cue to grab my eyes onto the impending danger. I'm sure you would have thrown something in if you had more time based on the polish of everything else.
This is a great entry! It really has me rethinking my next game jam to be more focused and polished with my execution because I love what you've done here.
