lovely puzzler!
I'd love to have undo button and maybe... can't we also have a private bathroom for some bedroom? O:)
... maybe you could have windows + bonus when a bedroom get's one
I've had multiple requests for undo, so I'll try to find a good way to include it!
I considered letting bathrooms attach to bedrooms, but decided against it to keep the rules streamlined. I also thought about including windows, but figured there was already enough to think about. But as more people play the game I'll get a better idea of which ideas might be feasible for future versions!
