Download of ChouXiang 1.2 for Mac was available from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The program lies within Games, more precisely Action. We recommend checking the downloaded files with any free antivirus.
From the developer:
ChouXiang is an abstract shooting game. It is operating system independent, and the source release requires Python (http://www.python.org) and Pygame (http://www.pygame.org).
