Jenga, but cooler.
Sling a sticky hand against a block tower to bring it down piece by piece. Your aim will drift as you get ready to throw your hand, so timing is key. Along the towers will be several explosive barrels that are set off by contact, so be sure to aim for them to speed up the process. Each level has a treasure chest at the bottom, and if you hand can grab it, the level is complete. Solid physics means you can strategically take down portions of the tower to topple the rest above them, which yields a satisfying downpour of blocks as well as a great deal of progress to finishing the rest of the tower. Think you have the skills to break down every design available?
