Sorry, I actually didn't implement the difficulties and forgot to delete them. Lack of time. I know, the fog was a problem in lower parts of the map, I didn't manage to really balance it out. Main navigation in that area was supposed to be a map and scanner, but I suppose it wasn' t really working as intended. As for worm... It's not a glitch, I knew I could not balance it properly, so the worm is basically a scripted event for the first descent, I didn't want to make it too annoying. Other creatures come in later. Thank you for the review, it really helps!
