I have just uploaded a new game for the gp2x. "Oh! The Humanity!" is a series of mini-games based on the most popular disasters in human history.
Download version 0.3.1 as 0.3.0 has a bug in the second level.
It needs pygame to run, and I should warn parents that it's probably not suitable for young people, as it contains adult themes including violence and religion.
Incidently, does anyone know of a 3D library for gp2x python? Might it be possible to a wrapper for the tinySDGL port?
