Still have some work to do on the walls to make them a bit less hedge maze and bit more forest, but things are far enough along now where I can show off a couple of screenshots. 
Here’s a terrain shot:
And, here’s a sample map generated using the new forest “architect” I made for the level:
I really like how the maps have turned out. They tend to have one big forested area, but with lots of fun side paths into smaller areas. 
Arcadia is a one floor side dungeon that will appear in 50% of games. When it appears, its portal will spawn on Tower:3, and the unique Actaeon will always spawn within it. Games where Arcadia appears will *not* have Tower:1 & 1/2, the two are part of a dungeon set (the first in Demon), only one dungeon in each set spawns each run (similar to Lair sub-branches in Dungeon Crawl Stone Soup.) This also means you may finally be able to run into West and Headless in the main Tower again…
Still a bit of work to do for this build, but I’m hoping to release relatively soonish. Stay tuned!
I’ve found Tower 1 1/2 is really helpful for getting some builds off the ground – have you considered offering portals to both levels and collapsing the entrance to the one that’s not taken or something?
Hmm… that’s certainly a possibility, and I hadn’t thought of that.
But… part of the idea behind having dungeon sets is prioritizing adaptability and dealing with situations as they arise, rather than knowing ahead of time that you’re going to have a certain set of encounters. But to your concern, I would consider it a problem if this makes some builds unacceptably difficult (though not if it is just *more* difficult
), so I will keep an eye and ear on it. 
Does it mean West will still be generated in every game? I think it is boring to have guaranteed Leadership etc.
Oh, no.
“Boss” spawns are only 100% in their home dungeon. If Tower: 1 & 1/2 is not selected for a given game’s Tower map, West and Headless only have a chance to appear instead of being guaranteed.
