That program is great, it's the best; I have fun watching masterful things.
The graphics are excellent, the only issue is that it runs slower on Windows 7 compared to XP and Vista.
It's not bad, the graphics are good, and it doesn't freeze or anything. At first, I find it fine, but after a while, I honestly get a bit bored, especially moving from one place to another.
