Two small comments,
1. Though the flag icons are drawn directly from the game, they're ruddy impossible to make out on a laptop screen or tablet - the kanji makes them all look life a mess of black with a red edge. I relied entirely on the mouse-over text to work out where cards were from. The icons may want to be made bigger or the letter made smaller, if that's not a massive faf.
2. At some point in the game, a flashing red/white square border appeared over the Port for me, but not my friend. I could never work out what it meant, but it didn't seem to affect the game. It never went away, and near the end of the game a second one turned up over the tea fields. Once I read the rules properly I might work out what it was trying to tell me.
Thanks again for a lovely bit of work!
