I was a bit annoyed by photosynthesis not working as expected. In one of my first games, I used algae to create oxygen. However, this did not remove carbon dioxide, and the overall gas pressure in my base mysteriously kept increasing. I know it's not a physics simulator, but given the name of the game I expected a bit more realism around oxygen production.

Overall the game is a strange mix of physics sim and quirks that don't make sense. For example, industry produces heat and heat spreads as expected. Solid, liquid and gas phase changes happen more or less as expected, leading to fun stuff like steam explosions. But then heat can be deleted in unphysical ways, heat can't be radiated away into space like in the real world etc.

The heat management is one of my biggest frustrations with the ONI gameplay loop. You go from gradually adding niceties to the base like lighting and plumbing to immediately needing some unholy water-cooled system that uses more power than the rest of the base combined, is stupid expensive in refined metals, and doesn't even permanently solve the problem because soon the heatsink waste pool is boiling and searing any dupe that walks past the general area. Oh and you have to do all this before the greenhouse gets slightly too warm and dooms the colony to starvation.

Heat management is super easy with aquatuner and steam turbine, you only need some steel and plastic, which are not so hard to get. Personally for me ONI heat-management is one of minor dissapointments, I think it would have been much more fun and deep if this system was more physically accurate.
