It's even more living room 2 changes (it is the most complex room in the game so it ended up needing the most balancing lol)

-Door characters will wait a tiny bit to enter your room if somebody else has, preventing situations where you have to deal with both at the same time, which were a little annoying

-entity 01 attacks you a little slower in hard mode.

-using the music box on virus toad while he is fully down will lock him in for a little bit (a visual effect of him becoming a little darker will show this effect)
