6595 points! Feel like that's a good score :)
I've played your previous games in other jams, this one is a bit different, but I think in a good way. This one is simpler, but at the same time more polished. It feels like by having a less robust main mechanic you had more time to focus on every element of this game. The effect is great! I was genuinely happy, when the game allowed you to play after getting the last piece to go for the high score. Thanks to the indicator, you know exactly where the planets are going to be placed. Thanks to the instructions you know what's the order of the planets. Gameplay was clear from the beginning, and really enjoyable.
Graphics are also great, but I have two gripes- I don't know if the planet textures count as "forbidden" shapes (not gonna subtract points for that, though). The other is- the color of the first and sixth planet looked too similar to me. I dropped a wrong planet a couple of times thanks to this :) Again, not a huge issue.
Audio is there, and it's not annoying, but could be more. You could partner up with someone who makes music or use some that you can use for free for non commercial use. Check out https://mobygratis.com/, maybe you'll find something you like ;)
The use of theme is on point. The space is limited and it affects the gameplay in an interesting way. Cool :)
Over all- I really enjoyed your game. I think it's one of the best ones I've played in this jam! Keep it up!
