I think my changes in MainPlayerScript last night got overwritten somehow, so I added them back. Currently, there is a bug if we build the game for Webplayer. One reason is because of the file io that we are doing. I believe we probably don't have permission to write files to disk when playing through a browser. A possible solution is to use PlayerPrefs to store the information. As mentioned, I will continue to work on boulder generating script, gas-wind tunnel interaction, and update the plasma model.
