Possible color vectrex lost games

home.earthlink.net/~jmorg/vectrex/VecColor.htm I know for a fact that there were color games produced for the vectrex, made possible through the spinning wheel motor on the vectrex VR headset. (The console came out in the 80s, pretty crazy stuff) But sadly the console died due to the video game crash and was never revitalized after, despite Milton Bradley owning the parent company. I want to know if there were any lost games made specifically for the prototype color console, as a lot of work was done on the Vectrex before the crash.
