It's there now. I don't have java and just experimented with some minor changes manually just to see what'd happen. One o my resistances to changes is that the enemy really doesn't care about your preferences, so mostly I just fight against whatever comes along. It's good fun and I doubt that any changes I did would make it any better. Also, making changes directly teaches me how lua works. It's a multi purpose package.
There is no script in the download, just pgn files. The 5 star is for the older version which I have and use.
