I have made a few changes to the 3D engine for a boardgame I’m working on.
The army markers are on a pedestal with the color of the player and the way the army is drawn on the marker is better.

Also the army markers and the question mark thingies are always facing the camera.

I’ve also changed it so you can use the QWEASD key and the UP and DOWN key to move around the space. SPACE toggles auto-fly (you may have to click on the screen first to make it register key presses. And it requires flash 11.4  minimum.
