This is Tumbledrop, a game I made. http://tumbledrop.com
You can also play the original PC version of the game here (browser based, but uses the Unity3D Plugin).
Just a little history, I used to work doing artwork for games like LostWinds and Rollercoaster Tycoon 2+3, but I went indie in 2009 and this is my first iPhone release.
I posted Tumbledrop on Neogaf a while ago, and some Neogaffers helped me out a lot with the testing. I had to put this on hold during part of last year, but it's finally finished and comes out on the App Store tomorrow.
