Dear diary:

Day 1: So much to do, so much to explore, this will be good!
Day 2: Found a cute animal, it poops out coal, might be useful for something.
Day 3: Tapping into electricity generating research.
Day 7: Powering up coal generator, feels like I'm an inventor.
Day 10: Colony is nice and comfortable 25°C, there's CO2 everywhere though, breathing's difficult.
Day 11: Utilized algae to convert CO2 into O2, that was timely.
Day 12: Life's good.
Day 17: Found a fish in a pool of yellow water, tasted better than the dirt bars we made. Dirty oxygen everywhere.
Day 25: Algae supply ran out, installing an electrolysis setup to make O2 from water. I'm a chemist now.
Day 29: Upper parts of colony are quickly getting filled to the brim with hydrogen from electrolysis, moving deeper down.
Day 36: Colony is now upwards of 40°C hot, everyone's suffering from heat, no sight of cooling in the near future, buckle up everyone.
Day 44: Some sickness struck the colony, there's urine everywhere, replaced outhouses with lavatories.
Day 47: My friend Ruby died from suffocation when she got stuck during excavations, R.I.P.
Day 58: Clean water reservoir is empty.
Day 59: There's urine everywhere. Again.
Day 61: People are stressed and ate our remaining food supply in a single day, others are vomiting or crying. Some are even straight up punching holes in the walls.
Day 62: Oxygen levels are getting low in the colony. Camilla and Otto didn't make it.
Day 63: Turns out dirty oxygen carried some pulmonary disease with it. Not good. Not good at all.
Day 65: We buried too many in the span of a few days.
Day 66: Feeling stressed and weak, Devon starved to death today. Am all alone and next.
