Interesting little game--not a theme you usually see! The game design was pretty fair; I understood the theme and goals of the game right away, and I didn't get lost or confused.
The audio was rather hell-like, but not deliberately, I think. It was annoying, to say the least--at the very least, the loop should have been longer.
The graphics were fine, given the time constraints. Unfortunately, I didn't really get the feeling of being in hell. There was no real sense of horror or doom.
Also, I found a nearly game-breaking bug: in the 2nd level, I got caught in a wall. While I thought this would probably end my game, it turned out to be a way around the level's puzzles! Still, you might want to fix it.
Finally, while I commend you for coming up with some new questions for the gatekeeper to ask, as opposed to the usual Riddle of the Sphynx-type stuff, I got caught on the second question on the third level, and, lacking any way to save and come back, that ended my game. Maybe a hint feature?
All in all, a fun and different little game with a few flaws that could be mended. Thanks for writing this game!
P.S. Please don't bother going to try and review my game--it never got finished, so there's no game posted there.
