I released an iOS game called Blitz Blok a few years ago. It's currently a free download since my server for all online functionality went down. You should check it out and tell me what you think.
I have a much nicer version in development that uses Game Center, better graphics, and retina support since the game was initially in beta in 2008. I'm looking for suggestions to make the game better.
