Hey Dr. MortalWombat. This is really a nice game. I totally missed that one first. I love the game and it reminds me of Fallout Shelter.
But I have some problem solving the game. I am suffering from oxygen problems. I tried a lot of things as I read that the intial floor has enough oxygen. So I built ventilation in all the flowing floors. First that seemed to work but than the oxygen level decreases and my people died down there. I have no chance to build more ventilation as all me mines near to the surface a depleeded.
Can you explain that ventilation thing once again for me?
By the way: The oxygen level is hard to read on real hardware as the contrast of both colours is quite poor.
Anyway a great game and thanks for the help
