The Infernal Magnet talent is almost pointless. There should be an XP bonus for "unfondled gems", but you should still get Brilliant if your gems make it back to the cave.
For me, this game is information overload. At all times I have to track the current price of tea, the current price of opium (and the direction the prices are headed), my supply of opium, my supply of tea, any jobs that are open, how many ships I have available... phew, I'm done.
There's a bug in the sound volume. If you mute the music and then return to the page, you have to change the music volume before it recognizes that it's muted.
One ting I like in pinball games is when you get to launch the ball: crank all the way down and really smack that sucker. But the plunger is so feeble! Still a great game.
