Well done on your game! I really - and I mean it - really like the concept, its super creative. Its ashame there are quite a few bugs in the game. I started with a familiar place, then played the level with three celestial bodies, and then the speck, which didnt seem like the intended order. My level progression also seemed to disappear when exiting menus - I am not sure. I had the same as the comment below me, I didnt see I could move more than one celestial body until later (though I am still not sure what determines when you can and cannot drag one.
Nonetheless I got the gist of the game, and it was actually quite fun. Artstyle is great and SFX do the job. I would've maybe liked more feedback on some actions, like a level complete celebration, swishy sound effect when dragging planets (I know it doesnt make sense) etc. Realistically though, how much can you ask for in a jam, you already did super well.
I write too many emails, so I am always inclined to end these comments, as I do for emails. Normally I resist the urge, but for some reason this comments feels worthy of a proper ending.
Kind regards,
Casper
