Meanwhile I feel like Prime 4 you are going in through the front door but then immediately detouring to the breaker room through the vents. Also I assume loading is a factor in being able to mix zones together, I found it a little rough on the Switch 1.

Yeah it’s a problem for overworlds with enclosed sections. I feel like the Zelda series actually does an okay job of including variety once in a while, for instance in LttP or OoT having parts of the dungeon have multiple entrances or parts that feel like the overworld.
