The 3D engine is wonderful, unfortunately I was not able to change the colours of the 3D Cube, not because I couldn't remember the colours ;), as it locked my mouse to the camera. Well done, superb concept and brilliant graphics. Well done

The game was supposed to have 3D complex shapes to make the use of 3D environment, but I didn't have the time. To do it. As for colors, they actually do change by using left and right arrow keys. Then you press Enter to select the next cube. The whole gameplay mechanic was tested couple of times so it should work.
