Touch The Musicis music game, similar to Guitar Hero and Tap Tap Revenge, for Windows Mobile 6 onwards.
The Options Menu doesn't work yet. You can tap the fret buttons on the lower part of the screen or you can use LEFT UP RIGHT hardware keys to play. If you want to quit the game, just press the RED (end call) key.
Please install on device memory for now, as the cab utility from windows sucks big time and I still haven't got the patience to write the .inf manually and see if it works.
