After this run, I'm more than convinced a 0 escape run is very possible! How long it takes for me to get such a run is all dependent on RNG...
First escape was impossible due to an intruder stepping on a trap at the same time I'm disarming the Brutus Basket trap
The other was an intruder managing to trigger the fan trap and slip away in the lobby while I was busy trapping in the Basement and Band rooms. (should have gone Basement, Lobby, Band, but didn't see lobby play out until after I captured in Band)
