found a game breaking bug. i went into the save room and i was unable to exit back to the portal room, or any other room i built that was adjacent. saving, reloading, and quitting to main menu and reloading from there didn't help.
There's some more info on how to connect rooms in the game, which might've been a bit hard to understand before. Also, there have been some fixes to the base code, so if this was indeed a bug, it was probably fixed in this new version.
