Really cool game, enjoyed it.
I liked the space idea with different planets and the sense of progression with space stations, ore, more cities etc and that you actually have to manage your population a little bit with cities vs. factories. Watching your numbers going up and colonizing new planets for building is very satisfying.
Cool to see that you actually have procedural generation and water shaders etc. working on a sphere haha.
Maybe I have just not played long enough for that(!) but I would have loved some visual feedback about what you're building like actually seeing the space stations and cities etc. The planets felt pretty small, maybe some more sense of scale would be nice + seeing what the planets look like in the solar system view. I think the "space building to make numbers go up" idea isn't the most creative ever, but well made and cool to play. Nice job!
