Welcome to the weekly iPhone Quality Index (Qi) games round-up, giving you the LOWdown on the HIGH scorers every Friday on these hallowed pages.

As you may already know, Qi trawls the web for iPhone game 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, and TouchGen) to establish a single definitive Qi score for each iPhone app and game.

Don’t You Forget About Me

Dashing onto the Qi leaderboard in pole position with a 9.4 Qi rating comes the Pac-Man inspired Forget-Me-Not, whose triumvirate of outstanding reviews virtually guarantees nobody will do any such thing.

Nyarlu Labs’s self-confessed “tiny little arcade” game distinguishes itself from Namco’s dot guzzling maze wanderer by rocking automatic weapons to obliterate the nasties, though overuse can – ahem - backfire if you’re not sufficiently careful.

While maps are procedurally generated (so exploding monsters alter the landscape on the fly), Pocket Gamer notes another important characteristic of your surroundings: “There’s also the option of scraping the sides of the maze...to both gain speed and power up your character.”

More speed, less haste

Retro flavoured goodness of a platforming variety has also raced onto our chart, as Physmo’s colourful insect female collects coins, skulls, and compliments aplenty.

In Mos Speedrun, your mission is to finish the 20 zombie and scorpion infested stages faster than a jet-propelled Usain Bolt with a plane to catch, before comparing your feeble efforts with the Game Center community.

There’s no room for even the smallest margin of error during the hot pursuit, as Slide to Play details: “When you're trying to get a speedrun trophy, you'll have to replay the level over and over again, studying enemy behavior and looking for ways to keep your momentum going as you navigate the terrain.”

Gunning for glory

Gunner Galaxies completes the holy trinity of nostalgia tinged success stories on Qi’s dynamic listings this week, with Atari’s classic coin-op shooter Asteroids serving as the spiritual basis on this occasion.

Fluik’s 140 achievements, 120 upgrades, and 25 missions mean the game’s longevity isn’t in question, but whether your thumbs will ever be the same again after a marathon session is less certain.
