Thanks everyone for the so nice comments !!! Since the end of the jam, I'm working on an enhanced version of the game, with all your game design advices :)

Fun puzzle game, though the info boxes keep duplicating sligthly obscuring vision

Nice little puzzler this. Would have like to see which placements were available without having to hover over them with a body, but i got there in the end ;)

Nice tunes in the background! It took me a while to understand what was going on but once I got it I was hooked!

I love the planetary scale as an interpretation of the scale theme! I agree with others about planet placements being a little unclear but I really liked the puzzles!! 

I love the concept of a puzzle with celestial bodies with requirements for each body. The puzzles are hard enough to be fun to solve. I struggle a bit to know where I can put the bodies, a grid (maybe stylized as stars) would be nice to have. It looks really good and the art style is pretty solid.

Nice work!

Interesting game concept.  Nice graphics!  Great work!
