Each Friday Apple gives away a free app, an this week the pp is iBlast Moki 2 HD.

At first glance this game looks to be an Angry Birds clone , but it’s more complex than that. It’s more of a Rube Goldberg type of a game. You build a solution for each level out of cute little characters, each with their own special skill. There’s far more to the level than just firing things out of a catapult.

You can watch the tralier after the break for more details, or you can head on over to iTunes and get the app.
