Wonderful
Your depiction of hell may be one of the better ones I have seen around. You did a clever and wonderful job on the artwork (simple yet very effective), the music felt more like an ambience, which really added to the feeling.
The game was indeed difficult, but its not impossible. I played through the whole thing, and thats something that rarely happens on a flash game.
I did laugh a bit at the very end, I never bothered saving, being hit by the most unexpected trap in the game... and it was the only key I needed to unlock the 3rd challenge. Tricky tricky!
