This is my first post here, so please be gentle!
I've just finished developing a GP2X game for the current GLBasic/GP2X.de competition, called B'lox!
It's a puzzle game, where you need to move Sliders onto pads of the same colour (sounds exciting, doesn't it?) With 100 puzzles, it should keep you busy for a while (there's a puzzle editor too, for the creative types out there).
The game is played either with touchscreen (on F200) or D-Pad/buttons.
Here are some images from the pc version (identical to the GP2X version).

Grab the game from HERE (approx. 2.7Mb. Includes both pc and GP2X executables)
