Pencel Games' popular XBLIG physics puzzler Gerbil Physics debuts for Windows Phone platforms this week, boasting an enhanced physics engine and a collection of new levels.

In the Gerbil Physics games, players use a limited number of explosive items to demolish structures and get each level's gaggle of gerbil characters below a specific height threshold. The upgraded Windows Phone port includes new art, new music, and three times as many levels as the original XBLIG version.

"We've ended up pretty much rewriting the whole game from the ground up to suit the mobile platform," Pencel notes. "We're also being published by Microsoft Game Studios so you can earn Xbox LIVE Achievements and show off to your friends on the Leaderboards. That's quite neat."
