The rooms were big, cause, as I said in a few other comments they were meant for fighting.
But yeah if I remade this I would of made the rooms much smaller and had more visual gags like the coffee machine room. There was a cut portal sections where you would of gone through alternative and fragmented parts of the office (but as you can tell from the way everything looks the same ) I had to cut it cause I ran out of time and had to reuse assets. Almost all the rooms near the end of the game were made from the coffee gag room.
