Pyromaniac
Pyromaniac is a light-hearted Bomberman clone written entirely in Java, using Java2D for rendering and OpenAL (via a very early version of LWJGL) for sound. It is the first sizeable game project I ever completed.
You can download the source and binaries for Windows. I wrote this all the way back in high school so I make these files available on the condition you don't point and laugh at the code.
