Dodger is a holiday themed (free) game for Windows Phone that’s in the style of falling balls. But of course, since it’s the holidays, presents are falling and you need to tilt the phone to control Santa and avoid Santa getting squished. It has three levels of difficulty (easy, medium and hard) as well as a timed mode. It stores local high scores and there’s also an online leaderboard (but I should warn you I was king of it as of last night so try to overtake me :) )
You can find it in Marketplace for free. It’s fun, game play is smooth and it’s a great time waster. It fills that gap of time when you lose the remote to your wife.
As an aside, there’s an update coming shortly that will improve the speed on the hardest level as more objects are flying.
