Gamer details: Top-down scroller, one-handed play (mostly tilt with an occasional tap), brief learning curve, typical game <60 seconds. I tried to give it the aaaargh-just-one-more-time quality that I love about Doodle Jump and Canabalt. I know that because it's a space theme, I probably cut my demographic in half. Perhaps I'll re-skin with ladybugs and flowers and launch it as a separate app. :)
Developer details: Box2D, sfx from Soundrangers, music from uber-cool Finnish musician Jani Rantanen, artwork from the wonderful Creative Commons CC-BY library on the web, buttons generated on cooltext.com, source control git, main snack mozzarella sticks, development time about 1 month. Helpful code snippets from many of you on this forum, including John Hartzog's website that helped get me started with Box2D/cocos2d integration.

Riq and cocos2d-iphone both got a special mention on the About screen.
And last but not least, the promo codes:
