Jemini is a game library designed to allow creation of reusable features. How many times has someone implemented the aiming on a first person shooter, or a minimap on a real time strategy? Jemini comes packaged with lots of behaviors out of the box, with the ability to easily author more.
Jemini uses Phys2D for physics and Slick for graphics and input.
Please note that the Jemini project is not actively being maintained. To find other Ruby-based game libraries, we recommend visiting the game libraries section of Ruby Toolbox .
