Short Fremantle feedback: the app installs correctly but doesn't leave any icon in the task launcher. You need to launch it via command line.

Then... is it just me or the balls in the white line are considered out? I know this is the typical argument in any tennis play, but I don't know whether it's you willing to bring more realism to the game (a referee that makes mistakes) or is a plain bug. Yes, it could be me just complaining because I couldn't but seriously those balls touched the white line.

Interesting game! Loooking forward to its consolidation.
