I don't have much of a plan if I'm being honest haha, but I'd like to at least make a couple more themed around a desert, the seas and some snow or ice.
My current workflow with these is really just going with a vague sense of what I want and then sort of figuring it out as I'm crossing that bridge. Actually, Doomcrypt was initially meant to be Doomdune but then I saw a tweet about some Warhammer vampires (I think) and just sort of turned around.
Ah you know what, I was thinking about maybe updating Doomgeon since I've figured out some stuff and feel I can improve on it with some of the feedback I've received from other commenters.
