Angry Birds Friends

What the 2009 slingshot game is

This is a physics puzzle game built around a slingshot, with the same core loop as the 2009 original. You pull back, aim and release birds at pig structures, and the goal is to knock out every pig on the level.

It suits people who want the original game's feel, and people who enjoy working out a shot before taking it. The listing describes it as a retro experience rather than a remake with new mechanics.
