I didnt have any problems with the controls, and the game runs smoothly on my 2G iPod Touch. The graphics are great, but creepy or tense music would be cool, as well as more weapons, and maybe unlockables linked to OpenFeint Achievements (like alternate character and zombie skins, or special weapons)? Just saying. Anyway, right now its free, so everyone should definitely check it out!
