We have the first game especially developed for the HTC HD2, it’s an OpenGL game that will though run smooth on other WVGA devices too, such as the HTC HD, Diamond2 or Touch Pro2.
The idea is to guide a UFO to the middle of the screen through five levels of difficulty with 12 levels each, the only rule being that you can move any object in four direction with the condition that it hits another object. The game is available as a free trial but the full version is commercial and costs around $4.4 (2.99 EU).
As far as you have a device running “Windows Mobile 5, 6, 6.1, 6.5 or 7” (our note: 7?) with at least 8 MB of free RAM and screen resolution of 240×400 or 480×800, you can play the game.
