Contamirun

You play the role of a survivor scientist trapped in an underground research lab situated deep within a treacherous cave system. The lab has been contaminated with lethal gas. The only hope for escape is to skillfully navigate through the complex's many perilous rooms, corridors, and staircases, ultimately reaching the surface before the gas fills to head level killing you.

There is some bug with the html5 build, please download the Windows build for a better gameplay experience.
