Yeah sorry, apple is not a big fan of blocking devices off unless you use hardware requirements that older devices don't have.

Since, I don't use (for example) a front-facing-camera in my game per se. I can't block out iPhone3GS users.

I think the WTF was more about the requirement itself – why would the game require a retina device?

In any case, congratulations on shipping your game!

I think "wtf?" is in response to it being both "Compatible with iPhone 3GS" and "NOT compatible with [...] iPhone 3GS"

Supporting non-retina can be a lot of extra work.

Is it just because you have to have different size copies of graphics, and other such adjustments?

It means all your graphics have to be in dimensions divisible by 2, or you have to change how you lay things out if not (and do more work to scale odd dimensions). Even when everything is, graphics can look terrible when you resize naively, depending. Sometimes you have to recreate graphics manually at different dimensions to get better antialiasing and things.

Damn, you really know your stuff, props.

Anyways now you guys all know why I didn't support non-retina devices :)

Indeed. Plus the graphics where too intensive for older devices like the iPhone3GS.

The interesting thing you'll find, as you continue to grow your capabilities, is that you can eek out more performance where you thought there wasn't any in the past. Keep up the learning and the great work.
