Great game! It's great how much old areas expand over time as new paths open up and new resources become relevant. I liked Increlution a lot and so far this is better.
Some more specific comments:
1. I initially got worried that I was going to run out of air and die when the Area air in Talos got exhausted, and didn't understand why the air tanks weren't resupplying it. IIRC my personal air meter wasn't visible yet at that point.
2. It would be nice to be able to turn off the air recycler in Laurion, or have it turn off when all the air is full. Or rebrand it as something else where it makes more sense that we can't turn it off.
3. It's surprising to me that the water recycler doesn't use power (in any location).
1. The personal air meter becomes visible as soon as you put on the emergency suit. If you haven't done that by the time area air runs out, you will die.
2. It's already mentioned that there are some emergency backup systems in Laurion that you simply can't turn off because they're considered essential. The air recycler (running at minimum power) is one of them.
3. I've planned to make the water recycler use power for a while now, but was always wary of making such a huge change to balance. I now have an automated balance tester, which should make it much easier to test that type of change without having to get people to play through it and get their opinions of how much easier/harder it makes the game.
