Room exits and entrances
I’ve decided to do proper room transitions like the 2d zeldas. I could just have done a hard cut between rooms but I always think that doesn’t give you a proper sense of space, so it kills a lot of the fun of exploration. That does mean dealing with multiple coordinate spaces though (there’s no such thing as “world” space any more).
Still, I can walk between rooms, which is nice.
To keep things simpler, I’ve limited it to one exit/entrance per side. That slightly restricts the available room designs but not much I think.
