iPhone: Perloo: FREE (Reg. $1)

You’ll find the rest of today’s best iOS/Mac deals in the Games/Apps Guide and here’s the latest Free App of the Week.

Perloo is a geometric fairy tale. Abandon your assumptions, solve a series of mind-bending challenges and find your way to the true world.

Perloo is a compact one-of-a-kind puzzle adventure that challenges you to think outside of your comfort zone. See how the real world influences the virtual one – and vice versa. Perloo plays with physics, quantum mechanics, philosophy, optics and perception to create a world with rules of its own.

Perloo is a ludic experiment, perhaps even a philosophical proposition. But most of all, Perloo is an excruciatingly hard puzzle game. You might cry.
