Here is CG Madness, a small game similar to Marble Madness.

It has been ported using gl4es.

Note that there is no sound at all, and the game has not a lot of levels...

Nub are setup to have mouse buttons on Left Nub and Mouse movement on Right Nub. Mouse look is activated, but you can also rotate the view with the Shoulder buttons, and Zoom in/out with {A}/{B}.
Jump with Space or {X}

On CC (and Rebirth?) model, I suggest you disable reflect (F2 in game to toggle it)

Tu use shader (warning, slow down the game), create a file named .es in appdata/cgmadness that contain just the number 2

You can find a video of the gameplay on the Pandora here: https://www.youtube.com/watch?v=TjojDOqJ-wA , thanks to Ingoreis.

Sources are inside the PND.
