INCREDIBLY ambitious project. I'm impressed with how much you got working. I noticed a couple bugs with repair where it displays the old number after repair til you go to another part and then back. But still, this is quite a lot of design work to juggle. I think it is definitely wanting some ambient noise and sfx work, and probably a gentle backing track, but the idea is compelling enough to get my attention, at the very least. I think my biggest pain point was trying to scroll out or find asteroids, but based on the scanning feature, I assume that just didn't get to implementation, and god do I know that feeling of needing to drop a feature for time.
Good job on your second game! You should be proud!
