Beaver's Revenge Free for Android through Amazon App Store

My kids used to be obsessed with Angry Birds when it first came out but they've since grown tired of propelling the multi-colored birds straight at those mischievous pigs. They even tried Angry Birds Stella which introduced a few more birds targeting their swine rivals. I found this game on the Amazon App Store and it's quite like those two earlier games because it also uses a sling shot as the central part of the game. There are four different worlds and 80 levels, but I don't know how long my kids will be engage with this. Good thing I got it for free so I won't be dismayed when they get tired of it again.
