I created an account to talk about this.
Right now, you can't remove a room that serves as the connection to another room. This makes organizing the optimal usage of space a bit of a pain.
Off of the top of my head, here are two idea for handling this:
- Allow a room to be replaced by another when constructing a new room.
- Allow a room to be partially deconstructed, leaving a "blank room" that exists only for connection purposes. You could then build over the blank room when constructing a new room.
I like the second one better than the first, as it would make the construction menu much less cluttered.
I know that the trope of a random person on the internet giving design advice on the forums is cliche as all get out, and you've probably thought this out already, but I just wanted to toss in my two cents.
