Puddle is a game made by a bunch of students that was picked up and distributed by Konami for the PS3 and Xbox 360. Since then it has been ported to everything imaginable, and finally is making its way to iOS. You guide a number of different liquids with different properties through environments via the iPhone's tilt controls. It's almost like it originally designed with the iOS in mind. The trailer explains more about the visual mood and variety.
As mentioned in the title, it will released on August 1st, and will launch half off it's original price at 2.69€.
