The term 'contre-jour' refers to a specific photography practice in which snapshots are taken with a light source behind the subject.
Unsurprisingly, then, Chillingo's environmental puzzler of the same name also focusses on light, tasking you with navigating several monochromatic landscapes in search of its warm glow.
Playing as a black blob named Petit, you must utilise tentacles, portals, and slingshots to reach your goal, as you morph the landscape around your globule.
Chillingo has added an all-new chapter (Moonlight) to its popular App Store puzzler, which introduces 20 extra levels to explore.
The Universal edition - Contre Jour HD - shot into Qi's Top 10 iPhone games list of August 2011, so shouldn't disappoint anyone who grabs it after the update.
You can buy Contre Jour in an iPhone-only package for 69p / 99c, or pick up the Universal HD version for £1.99 / $2.99.
