Living room 1-

Wario will move slower in the hard variant, and give you extra time to check up on him once he moves

Bedroom-

The circle has more consistent mouse recognition (hopefully), and a tip has been added to "keep the mouse ahead of the circle to track it better"

Also Luigi moves like 6% slower LOL

Staircase-

Luigis movement makes more sense, and is easier to keep track of generally

Living room 2-

Yendo kills you slower

Bonnet moves across the screen slower (especially if the monitor is up)

Lolbit is less of a flashbang and has more reaction time

Both bonnet and lolbit will not only move slower, but also less randomly

Virus Luigi's ads can no longer appear on top of the music box button, but it also kills you slower

Characters leave the doors faster (20% faster), but to compensate, the doors drain 14% more power

A smaller patch making all character explanations more clear should be coming out soon.
