Just when I thought I got all the bugs! I think the sound emittance plugin is the culprit.
I also agree gameplay is punishing-- perhaps in the future, cultists could emit a slight light radius? Maybe the retention of enemy map position is a bit much? It was a real crunch for our 10 day deadline, and levels were basically thrown together in one night.
Even despite all this, if you save at every checkpoint and utilize stealth mode, our game can be completed consistently in under 10 minutes.
Thanks for checking it out, and I'm glad you enjoyed the beginning!
