This is a new game called Touchdown. It’s been designed to make the most of the VGA screen on the HTC Touch Pro but should also work on the Diamond and possibly other VGA devices too.
It’s still in early development, so you’ll need to download the demo, unzip it and copy the resulting files directly to your phone and run the “Touchdown.exe” file with your File Explorer to play. You may also need to get .NET Compact Framework 3.5, but other than that it’s completely free and you can give your feedback on the game on xda-developers.com
