Really nice! Lots of different planets to visit, cool models, cool physics and everything. And I loved how music changes when you visit a different planet, that's awesome! The only flaw I can see is that it's a bit difficult to see whether you're going to successfully land a jump where you want it, or not, because the character doesn't have a shadow, and platforms have too soft edges - it's hard to see where the platform ends sometimes.
If you have the time, please rate my game, too. It's not that techy tho ) https://daromaru.itch.io/solar-crew
