2 things I really don't like. Ore being flung off the edge of the screen where you can't get it and ore flying five miles away from the explosion site. Otherwise I like the game.
I was halfway through the game and thinking I must be a pretty poor villain since I'm the only one without minions. Then I saw the minion tabs on the upgrade screen. /facepalm
Pretty nice little game. I'm always slightly aggravated if a game doesn't have a mute button though. (as I have other things running while I play these off and on)
Thanks! And totally agree. It's an undocumented feature :) You can press [0] [+] and [-] to control sound levels.
