Blocks and Tiles

Blocks and Tiles looks a lot like the rolling cube puzzle Bloxorz. I almost didn't download it.

Then I read the description and the authors indicated that it takes Bloxorz to the next level. So it was nice to see that they paid tribute to the original concept.

I'm not really sure what the other features are. I did the 20 free levels pretty quickly.  The additional 39 levels I didn't pay for.  If you have played them, please add to this description in the comments section below.
