I just love space stuff in general.
Contorls feel a bit weird and not what I expect (especially after playing a simulator with a very similar name to "Universe S&Box"; it's pretty simple but it's still mesmerizing
Not much you can do besides staring at the planets but I can see the vision here. Dev needs to implement new features because it's clearly work in progress. Good luck with reshaping it into a better game.
The simulation aspect probably needs work, but I learned we have like 3 extra planets - one fo them being a funny ellipse shape. That alone means it taught me something.
