You could have downloaded BlockDestruction1 1.0 for Mac from our software library for free. This free software for Mac OS X is an intellectual property of Matthew Tytel. The program is included in Games.
From the developer:
Prevent the blocks from hitting the camera by swatting them away with your right hand, left hand, or both hands. Challenge yourself to swat as many blocks as possible before they strike. This simple game uses API Methods like: Finger Joints and Hands.
You may want to check out more software for Mac, such as Descent 3, Eternal X or Treasure Seekers 3- Follow the Ghosts, which might be similar to BlockDestruction1.
