So, I don't have any ideas for mechanics for 3 characters. Namely :

-penguin

-damaged S.bunny.

-damaged S.Bear

What you have at your disposal:

A monitor with cameras (obviously)

Door controller

Door in the center of the office

of the right and left vents (you can only close one at a time).

Flashes on the cameras

Now, think of something interesting in the comments (if I like the idea, I'll add it to the game, and you in the credits).
