JGame is a 2D game engine that makes multi-platform development easier. It runs on the Java JRE 1.3+ platform with optional OpenGL (JOGL) enhancements, the J2ME (MIDP2.0/CLDC1.1) mobile platform, and the Android (2.1+) platform. JGame features sprites with automatic animation and collision detection, a tile-based background with easy sprite-tile interaction facilities, automatic scaling, sound, game state, persistent storage, and game options. The engine provides an enhanced graphics API with a fallback to simpler and more efficient graphics on J2ME and plain JRE. A patched version of the JBox2D physics engine that runs on all platforms is included.
BreakIn is a version of a classic pong-style game from the late 1970's. Move your paddle to hit the ball. Take out all the bricks and move to the next level. The game gets more difficult as the ball speeds up and your paddle gets shorter. A Java ME enabled device with CLDC 1.0 and MIDP 1.0 support is required. The version with sound requires a device with Sprint PCS extensions for MIDP 1.0.
