My entry for Ludum Dare 27 where the theme was "10 seconds". Little, short and kinda difficult game about two coworkers who work in a underwater lab. Then an accident happens and they must leave right away. The problem is you two only have one oxygen tank and no way to refill it. Ah! Also, your coworker Dave is unconscious. So you have to drag him around to help him breathe. You need him to activate buttons at same time to open the doors.
