NinjaBee's decidedly adorable city-building game, A Kingdom for Keflings, is the latest arrival on the recently launched OnLive mobile streaming application. As part of its welcoming celebration, the title will run players $2.50 (down from $9.99) through midnight on Monday, December 12. Better yet, anyone who bought the PC version of the game directly through NinjaBee's site are eligible to receive a free OnLive copy -- just email Swag@NinjaBee.com with the subject "Keflings OnLive," including the name and email address you used to buy the game.

The OnLive version is one of few games on the platform to be altered to include native touchscreen controls, making it a nice fit on tablets like the iPad 2 and Android devices. Keflings, you see, are meant to be poked and prodded, not manipulated with cold, unfeeling joysticks.
