id also remove the breaking tables mechanic you want players to feel safe but not know if one of the girls will ambush them
another idea is to give the girls a crawling animation and a detection if a player has hided for way to long in a vent or even under a table the girls can crawl in and ambush the player
for vents you could add a system where if a girl knows you went into one the girls will spread out to the exits and only 1 vent is clear of their ambush when you aproach a exit as the hunter girl is crawling behind you
when you goto leave a vent your either met with booba to the face or if you stall to long you get grabbed and see one of the girls crawl over you getting ready for some vent breeding
