Oh no, the apocalypse is here

On the year 2015, a serie of volcanic explossions lead to a massive leak of nitrous oxide, or NO, setting the beggining of the apocalypse. Three years later, a scientist called Orson Hargs created the OH filters, which may separate the nitrous oxide from the oxygen, and created the OH-NO masks. 

It starts like this but it's going to improve over time!

FIRST GAME OF OUR LIVES, so very proud of it
