Great job submitting a game! I really love this idea. Extremely difficult to pull off a game like this within these restrictions but you managed to do it! The only complaint I have is the resource rng. In my first two runs I never got any energy so I couldn't do anything and I just lost. I think on my 4th run I got to the core. It did take a bit of reading to fully understand everything but I felt like it was very intuitive and quick to pick up for the type of game it is.
I still don't quite understand why I need soldiers. I know the alien breach kills them but I seemed to be able to go without them and the alien breach event becomes a nonissue. This game made a great story on my third run. I was building up a base and I got a triple lava leak that destroyed everything. It was painful but a great moment! Last thing, the title screen looks amazing and I would love to see a fully realized game like this. Thanks for participating!
