Zuma is the second game I buy for my iPod Classic 5th Generation. The first one was a car simulator. Let me say it is crap. Great it was just 5 Euros.
In that occasion I saw the Zuma screenshot on iTunes Store and noticed it might be a nice game, as the type of game is very adequate to the iPod touch wheel.
After about one year I decided to buy it. The game is pretty nice and playable. I just have two complains. First, the music. It is always the same. I think it repeats every five seconds or so. Yeah, I know I can make my iPod musics to play during the game, but the music could be better anyway.
My second complain is regarding efficiency. The developers of the game know exactly the hardware where the game will run, but the game still have problems running there. Sometimes you notice glitches in the music, and more rarely, on the game itself.
