So, logically some creatures need more oxygen than others. At least, that's how i've imagined it. So, if that's the case, then logically some creatures can live in low-oxygen envirments. Basicly, a section of the config menue allows you to set the requirments per entity. You can put in a range. But, if it's empty (An entity isn't listed), it assumes the same range of a player. The defaults are zombies needing less air than you, and up to higher pressures (They're dead, but still have enough cellular activity to need some air), and skeletons are pre-set to need no air, so any pressures. (They are just bones held together with magic)
