Welcome to the first weekly iPhone Quality index (Qi) games round-up of 2011, which has been giving you the LOWdown on the HIGH scorers every Friday on these illustrious pages.

Launched in beta by Steel Media, publisher of PocketGamer.biz, Qi trawls the web for iPhone game and app reviews from the world’s most respected online and print sources.
Qi then applies its own magic formula to each site (such as 148Apps, Macworld, IGN, and Gamezebo) to establish a single definitive Qi score for each iPhone app and game.

Shapeshifting

Transferring onto iPhone from the famed Flash universe has proven a cinch for Armor Games’s puzzle platformer Shift! 2, as the heroine of the piece gathers up plenty of praise and keys on her monochrome travels.

The successor to the widely respected Shift raced onto the Qi chart this week, collecting a fabulous 8.9 rating from three reviews, all the while evading spikes, purgatory, and other nasty objects.

120 levels of perspective flipping action should satisfy even the most seasoned puzzling fiend, particularly when you consider 148Apps’s following words:

“Shift!2 makes things even more perilous by adding blocks that automatically shift you in 90 degree angles, and of course requires you to think in four directions on many levels to get to the end.”

Dancing queen

Another physics based puzzler has been tearing up the Qi leaderboard over the last seven days in the delectable form of Save Toshi, whose hot-stepping antics have attracted an 8.6 Qi score from the App Store judges.

Nitako’s eponymous and endangered star must rediscover her dancing shoes by negotiating an intricate path to the nearby dancefloor, which is where you come in.

The water that surrounds the young female is the dreaded enemy, as you fire off balls left, right, and centre to break and manipulate the scenery around Toshi without dropping her into the sink.
Pocket Gamer came away duly impressed by Save Toshi’s playful level design, which throws up “rotating platforms, giant man-shaped objects and Indiana Jones-style rolling balls employed. Sometimes, you even get to fire Toshi into the air by dropping a large weight on the other end of a lever.”
