Welcome to the Pyramid

Perpetual Pyramid is a collection of open source games and development tools.

The games are all open source and are mostly developed in Python using pygame and a number of other packages. The games utilize serge, a game engine that I built on top of pygame to simplify game development.

Games with the Online play available symbol can be played online through the browser.
