The visuals for this are absolutely spot on. The glossyness, the layering, it is very evocative.
The gameplay itself is fun, but I found myself struggling with the perspective. The instructions are a bit misleading in that you are told to click and drag, but the cubes don't work like that at all. This made it take a while for me to figure out the cubes. Catching the circles that are bouncing all over the place was fun once or twice, but I had to give up once you threw four of them at me.
Regarding the lag, I think Cronos Games is referring to the choppy movement of the spheres when you're dragging them.
Overall a fun package. A visually stimulating and unique game.
