The Xbox Live Deal of the Week program appears to be slowly making its way through all of the Windows Phone launch titles, temporarily knocking one or two dollars off of each game. The latest game to get the discount is OMG: Our Manic Game from Arkedo Studios. It’s on sale for $1.99, down from $2.99. Oh my gosh!

OMG is a vertically-scrolling shooter featuring neon-colored vector graphics. The player’s ship constantly fires, while tapping enemies makes them become manic and unleash a hail of extra fire. The game has got both Infinite and 5 Minute modes to blast through.  Our OMG review notes that it’s a bit light on content (as with many launch titles) but still plenty of fun. The gameplay is a little too plain for me, but if you’re into shooters, it’s currently the only Xbox Live game in town.

OMG is on sale for $1.99 for like, one week only. You can totally get it here (Zune link) on the Marketplace!
