I'd be careful with using the word "tetris" - the tetris company goes after anyone that uses it with cease and desists, etc.
I know you use "tetris-like", which is descriptive in any sane person's eyes, but when it comes to legal issues it's the money that talks, not logic.
When's the android version coming out? Is there an iPad version? How about a hi-res version for the iPhone 4? :-P
