Doors work again in 2.0.10. I have noticed you added in some areas zombies. After you added zombies to a room with the hospital levers puzzle cant be finished, even if you pull them in a correct order door to room with bolt cutter are still closed.
As for zombies they have a collision problem with other zombies, if you kill one of them in for example door, zombie behind cant pass through dead zombie.
Idk if you fixed a save rooms yet. But a save room in end of Arcade is still unavaible, as it doesnt detect ink ribbon in inventory.
