Touch The Music – Guitar Hero for Windows Mobile

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 level/game, just press the RED (end call) key. Please note that with the hardware buttons you won’t be able to net those multitouch points. A singletouch easier mode is planned for future versions.

Changes:

Multitouch working.
New menu system, with placeholder graphics.
New level (incomplete).
New resolutions.
