Red Block Remover 2 HD
Impressions : Very nice graphics and quite a fun physics puzzler. So, you need to get rid of the red blocks, but you can't get rid of green blocks and blue blocks are optional. Some blocks you can tap on to get rid of them, but others have to pushed, or have other blocks under them removed in order to get rid of them.
Quite challenging, and fun even at the early levels, and the learning curve moves up pretty quickly.
For those that like physics puzzlers, this one seems to be pretty good.
