Hello!! I just have to say that this is without any doubt the game that I enjoy the most... No words for it... In most games of the jam that I played I didnt even finish them.. but I did your 15 levels. Maybe its just that space and gravity stuff are really interesting things to me, but so far my favourite game.
The visuals, interface and sound effects fits perfectly the style. The only thing that I missed was some background space sound (not necesarily music) to avoid those silent levels.
Anyways, congratulations to the devs, 5 stars.
