With the current version of cave generation I'm letting rooms connect to walls of another room. I'm hoping that by allowing this it's possible to create almost town-like dungeons just by creating lots of rooms in a small space.
This is a section of a cave theme level view in automap. Those green spots are bushes... it's a start of more generic plant generation, no other than bushes are generated at the moment, but it will be a jungle when there are more plants. It's all getting back slowly. Rooms, corridors, stuff like that.
