I saw that too, doesn't look to thrilling to me. Maybe people just like the idea of having "Falling Balls" on their iPods/iPhones hee hee
i got the game when it first came out, and believe it or not the game is really fun, it gives you somethin to do when ur bored so i would suggest trying it.....
I would say the name also makes people download it, if you made an app called Blue Balls i'm sure it would receive a lot of downloads
