The Pipmak Game Engine allows you to make panoramic adventure games, in a style similar to that of the Myst game series. You can use static images or 360° panoramic views, allowing you to make game like any of the Myst series. It uses Lua for scripting, meaning you can make games using a powerful yet easy to learn language. Pipmak is available under the GPL licence. It is currently in a very early stage of development.
