Fireball Special Edition (aka Fireball SE) from Radiangames (that's me) is out now. It's $0.99 for the first week ($1.99 after that), and is a Universal app (iPhone 3GS or later). As a fee for posting about my own game, here are 3 free download codes:

Fireball SE is an object-avoidance game (like Tilt to Live or Geometry Wars' Pacifism mode). Here's the launch trailer:

After jumping around between XBLIG, iOS, and PC for the past couple years, I'm focused solely on iOS until Radiangames makes it or I run out of money. Next games coming to iOS are Ballistic, Inferno+, and Slydris (likely in that order). Hopefully there will be more after that
And just to weigh in on iPad vs. iPod gaming, I prefer iPad strongly because of my large hands (I'm 6'7"), but I rarely take it with me out of the house, unlike my iPod Touch. I generally find that any good iPhone games are more enjoyable for me on iPad.
