Thank you so much for checking it out! I've been trying my hand at some game development since around March, and this was the first thing I thought might be good enough that people would play.
It's good, I like games about space, but currently it's slightly unbalanced - not enough copper. I end up with 100 ignots of everything except copper, so upgrading further is grindy.
Thanks, you were absolutely right! I looked at the numbers and copper was out of sync by almost 40%. Your feedback is super helpful. I pushed an update, let me know if it feels better!
