Cubes & Spheres

This game is incredibly hard, but also addicting. I could see many giving up pretty quickly due to the steep learning curve but it's worth it if you stick with it. The mechanics and physics of the clicks are very nuanced and well done, though it took me some time to appreciate it. I first thought the click mechanic was interesting, then I thought it was unfair, then I started to understand it, then I thought it was unfair again, then I was impressed with it as I maddeningly tried to make it through level 2. I'm still trying to make it through level 2.
