Allright, maybe I'm just not that smart, maybe I'm not much of an adventurer or maybe I'm just lazy. I switched the levers 3 times according to the manuscript (all 4 of them), door opens (even when i had 2 different settings of levers cause the second time I just pulled some of them randomly ^^) but both times I died.
What is it you need to do exactly? If you don't want to spoil anybody's game, mail me or pm me! Thanks!
