Well this is a fun little thing, and hope to see it more polished up as well.
I did notice a few things though, for instance that Connia and Lemily appear to not have a game over scene, and as such they both seem to just bug out the cameras when they're at the doors instead of entering the office, which also seems to prevent Pink from entering as well.
Also I noticed that Pink and Star appeared to not have a model at the doors either which made it more or less impossible to prevent them from entering the office.
Honestly do hope that you continue to develop this one and polish it up more as the whole mechanic of using the air in various rooms to prevent the characters from reaching the office is kind of unique. Best to ya with this project
