Matt Martel's Mundue is the second kind of developer. He makes the reMovem app; it's a simple little game that has you removing colored balls from the screen (in order) and trying to completely clear the board. The idea is simple and fun, but the app has grown extremely complex; it has been downloaded over 6 million times, and is now available in thirteen languages across several versions.
Martel sat down this week to show off reMovem2, which is the iPad version of his app. The main difference, he told us, between the iPhone and iPad versions of the game is the screen size, but the fact that you've got more room to play with really opens up the gameplay. More balls to match can mean greater difficulty, but it also means larger scores. And though Martel started out with a single game mode, the iPad version incorporates four different modes, the option to add extra themes, a chance at in-app purchases, and, as he told me, lots of different opportunities with iOS 4 and Apple's upcoming Game Center.
