Glad you liked it. Sometimes the lighting can be tricky to strike a balance "dark" can add atmosphere or make it more difficult but at the same time... too dark and you reduce people to guessing and most will give up.

The part with the funnels was pretty dark. It took me banging against the side walls to figure out it was a glass corridor. And, since it was dark, I couldn't see the portability of the corridor. It almost caused me to give up, thinking I'd never be fast enough for what was needed... Nice map!
