When it comes to puzzles and the App Store, most games are similar: lots of eye candy, and lots of relatively easy levels. Mind Wall is different. For starters, there are no pretty graphics to distract from the core game. And then there's the game itself.
In Mind Wall, each "level" presents you with a moving, square wall with a bunch of openings in it. In the top-right corner, a shape appears. Tapping a spot on the wall marks that unit for removal; your goal is to create the right-shaped opening so that the shape can pass through. You can only remove one spot, however, so accuracy is key.
