Amazon's free Droid app of the day was "3D Mini Golf Challenge" by Digital Chocolate, which is the company that Mike_S works for.
My son and I have been playing it all morning and love it. The graphics are great and the control-scheme is simple yet fun - simply slide your finger back to set your power and release to shoot.
I do have a request from my daughter that you try to make it compatible with her Arnova 10 G2 tablet (running v2.3). It loads, but it doesn't display correctly - the holes and ramps are invisible.
