One of the best games I played in this Jam. Puzzles where awesome and fun, not to easy and not to hard.
Now I have few comments, but this are not neat picks, this game is perfect for this jam timeline. just feature suggestions. Would be cool to have procedural generation of world and maybe preview. More complex worlds made out of more than 3 spheres. And obviously more puzzles would be awesome. Maybe some where you don't just follow directions, but trying to solve for requirement, make world habitable for some species. Or something like that.
But really this are just ideas for a bigger game. This game is perfect as is. (It also works perfectly in mobile, the controls are so versatile that just drag and drop of touch screen was enough)
