Looks like the doors and elevators were bugged and activated prematurely. Normally there'd be a switch in the room beyond the blue and yellow doors that would raise a platform in the lava that takes you to the exit. In this case, the platforms were already up so you could just walk out. I don't know what I broke, this is gonna be a huge headache to fix lmao
Thanks for playing, sorry for the gamebreaking bug, and thanks for the critique. I want to rewrite my enemy AI one of these days because it's all very janky and full of bugs. I'll try to make the regular cultists more dynamic and fun to fight when I start rewriting their AI.
