I thought that this was a great game up until you get the hang of it. Once I played it enough times, I was able to beat it with 5 blues, and 4 greens, so once I obtained the greens there is a challenge, but after I got them. Easy Mode, really. The only thing that I didn't understand was the High Scores. I thought that I did great up until I looked at them; my score was 300,000; I thought that was pretty good until I saw that the top score was 1,000,000.
