With E3 preparations, E3 and then E3 wind-down taking up a lot of our energy here, we're not too proud to admit the Aussie-developed App of the Week has seen better, err, weeks. Never fear though, this week sparks its triumphant return, and with it one of the best games we've come across since its inception (all other titles have been great too though).

Monstaaa! from PixelElephant is a stunning little physics puzzler for both iPad and iPhone with full tilt controls, and some great level-design. The game's charming music and basic premise make it a must-purchase for puzzle fans and, honestly, I couldn't stop playing it throughout my E3 trek.

Your job is to feed the, always hungry, Monstaaa with delicious bugs! The base game-play mechanic is very simple - just tilt your device to change the world gravity and watch bugs fall down into Monstaaa's mouth. But there's numerous deadly obstacles that stand on your way - from smashing stones and locked down areas through deadly fire and spikes to winds and fire balls. Monstaaa's life gets even more tough when dealing with multiple bugs at the same time or with bugs that grow over time or... with bugs that eat other bugs! Each level has something truly unique.
