The game overwhelmed me with all the mechanics, but I was able to figure out by just winging it which does show pretty good design. Still, I had a long string where I couldn't find any planets to generate water, and I wasn't clear which upgrades would be more or less significant. I ended up running out of water despite water efficiency upgrade, a water upgrade, and two full miner upgrades.
I also wish there was music and more sfx works, especially because of the simulation vibe this game has.
Overwhelming aside, it's VERY impressive how much game you fitted in here. Like did you get sleep??
