Hi, thanks for feedback. I'm releasing an update today that should help new users, instructing them to start with a single room and find a good anchor, then build out from there. I think a bunch of users are getting lost in the setup screen, saddens me because theres a tonne of stuff that opens up once you get a basic setup working.

all that said, it never even occurred to me that people would want to floor lines to line up with real ones. The system has no way of knowing which direction you are facing when you first load the program, so its not possible to align it on startup. Check out the SNAKE minigame (turns your walls and object to grid/voxelized kinda objects) might satisfy you a bit.
