game has been sent in by William from the Puzzle Dungeon Advance Group:

My group has just finished our year long game project.
It's a puzzle game with 100 levels, and its a lot of fun.

The game has been tested on the real GBA hardware, and plays extremely well. It is very addictive, and has cool music and a polished feel to the graphics and interface. Well worth a try
