Apart from the 6 minutes 11khznses, some real navigation issues hamper this. Every bed is a huge jumppad straight up into the polygonal ceiling. The ramp to the kitchen counter is very hard to climb. You can get snagged by the couch section edges
There are reallife houses/mansions that can do the arena gameplay well, and I haven't seen many of them done :(
