Cute game! It took me a bit to realise you have to spam click the center to get points (I felt like I tried it and it didn't work but I guess I missed something), and once you get a bunch of planets it's really hard to click the smaller ones (though I guess that's a reason to avoid too much recursion!). Maybe it's just me, but the effect of all of the little upgrades is a little unclear. It's cool that it's an idle game that encourages some puzzle like thinking though, and I like the themeing :D
