Some feedback:

The UI needs some work. Running on an iPhone 3GS, it felt very laggy, many of my touches didn't register correctly.

Tap to rotate is an odd concept, and combined with the lagginess above, I was always moving when I wanted to rotate, or vice versa. Maybe two fingers to rotate?

Move the advertising. Having it right on top of the playing field caused me to accidentally click it when trying to move around a block, taking me completely out of the game.

A better visual distinction between blocks I'm allowed to move, and blocks I'm not allowed to move would be nice, I spent a few minutes of the first level trying to move the block that was already there.

Otherwise, I love the concept.

Thanks for the feedback. An iPad 2 was my primary testing device so I surely didn't give the iPhone version the UI love it needs.

This explains a lot. If my thumbs were 1/3 their present size, moving the blocks around on my iPhone probably would have been a lot easier. I recommend increasing the area you can touch to "grab" a block by at least 50%, and adding some sort of visual indicator of the position and orientation of the block outside the thumb-occlusion. Other than that, it's a great game.

Just an FYI: it crashes while trying to open it on my iPhone 3G (displays the splash screen, then exits to springboard.)

Love the idea, though. :)

@ghempton, if you're still reading these comments, it's likely you're passing a iOS 4 or 5 message without checking to see if the message is received.

I ran into this recently with a number of simple startup checks, e.g., if the device is a high-res ([UIScreen scale]) or if it's an iPhone vs. iPad ([UIDevice userInterfaceIdiom]).

Having it right on top of the playing field caused me to accidentally click it when trying to move around a block, taking me completely out of the game.

But possibly earning some cash if it is cost per tap. I sometimes think people who show advertising on their websites and/or apps must love tablets and phones because it is so easy to accidentally tap on an ad. I've done so many times, even though I'd normally never click an ad.
