Been a fan of the original game since my childhood, decided to try New Game Plus in my first time playing KeeperFX- I'm loving it so far, along with all the UI changes (that feel so natural that I almost didn't notice them, like WASD and mouse controls), but I'm getting flummoxed by Flowerhat.
Not on how to beat it; I'm just trying to figure out the conditions for accessing the secret room to the north of the chamber where you get the spiders. The access point starts as one dirt block, but it always changes into impenetrable rock by the time I can get there. Is there a time or gold limit involved? Is there some other condition I'm triggering by accident? I searched around, both online and in the forums, but couldn't find an answer.
