We're really glad for all the positive feedback, this was a fun game to make so it's great to see everyone enjoying it.
I wanted to quickly adress @omiya-games ' comment
We purposely chose to limit the amount of asteroids you can shoot to 1, these planetary systems are very delicate and it would be pretty hard to invoke that feeling of being pin-point accurate. That aside, setting up levels gets harder with each planet you add.
The trajectory of a planet does actually stop when going into the sun, but the radius where it stops is just a tiny bit smaller than the actual radius of the sun, so apologies on that one.
P.S: We didn't actually use Unity physics, our team member @mjex wrote a custom physics system for this game, so the Physics.Simulate guess was decent, but we just happened to have taken the long way around this time
