One of Java hobbyist’s favourite events is Java4K. FYI, in Java4K you create games, with any theme or genre, that fit in 4 kilobytes JAR archive file. No external resource, no external library.

For my entry, I submitted Bubo 4K. This is a simple colorful Chain Reaction clone with 20 levels to go. The gameplay is quite simple. You click anywhere on game area to start a first growing ball. Every ball that collides a growing ball will become growing too. Pass level’s requirement of growing ball. Easy but several challenges are prepared to hold you,

• Level system: white Lv0, green Lv1, blue Lv2, red Lv3.
• Every ball has different move speeds.
• Growing ball won’t last forever on there; they have lifetime depending on color (level). Higher level provides longer time.
• Colliding condition apply; Ball will start growing if hits with same color (level) growing one, except for white ball.
• A growing ball changes its color (level) after being hit. The order is green -> blue -> red.
• Two mode of gameplay, Fate mode and Skill mode. On Skill mode all balls cross over wall instead bounce and player can change direction of small balls by click on them.

The development is still on going. I’ll try to include sfx.
