simple tetris clone in cocos2d-x

Hi,
I’m porting my simple-tetris-clone to cocos2d-x, just the win32 part without sound is working now:

http://code.google.com/p/simple-tetris-clone/source/browse/#svn%2Fbranches%2Fcocos2d-x

if you see something that ca be improved feel free to point it to me.
I have the game running on an android device but is running in portrait mode, I’ll need to fix that first before uploading it.
I got the project to compile out of the cocos2d-x directory in win32 but in android is not that simple, somebody achieved this?

Another thing I noticed is that images of odd sizes in pixels are blurry rendered in win32, Is this documented somewhere?

thanks!
