I found this post by the developer himself on the Something Awful forums:
Everything Geared is free for labor day weekend. If you haven't checked it out, or haven't heard of it, Geared is a puzzle game with the simple goal to make all of the gears spin using gears from your inventory. It was the #1 Paid app once upon a time ago, and the brand has seen about 12 million downloads. So please check it out if you like puzzle games!
