This was really fun and I enjoyed it a lot. Great soundtrack, flicking the planets felt great, I loved the detail of zooming out and lowering the volume for those really epic tosses. I didn't get to the sun, darn.
I have couple super minor notes for you: 1) I have never played a game in this genre before. I think you're doing yourself a disservice in the description saying "Yet another Suika Game, but in SPACE." Not only is it an unnecessary way of painting your game as derivative (we all borrow ideas from other games), but it doesn't do anything to explain the game to someone unfamiliar like me.
2) I'd like it if the next planet appeared instantly after yeeting the previous. That way, when stakes are low and space is plentiful, you can get a little crazy tossing planets up into the solar system.
All said and done, this was fun, juicy, and complete. One of my favorite entries this jam I've played so far. Find some ways to mix up the formula (an asteroid ring surrounds the system in one level, blocking easy tosses?) and this would be fun for someone to play on mobile.
