There's only been three/four generations of handhelds (unless you count really old, poor performing handhelds like the Microvision), depending whether you seperate Gameboy Color from Gameboy. If you don't, the DSi is still a third gen handheld. If you do, by the same standard you must call DSi a fifth gen handheld. It's definitely not fourth gen, either way.
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
