IF YOU'RE LOOKING FOR THE MUTE BUTTON...
1) Go to any level. Doesn't matter which one.
2) Click on the 'Menu' Button at the bottom right of the screen.
3) Click 'Sounds' ONCE.
4) Congratulations. You have now turned off all sounds and music in the game.
-Sigh- The differences needed to be a bit more.. Noticeable. Not too much. But I'm sorry that I really couldn't notice a single grain of cat litter as a difference when the wall I'm trying to click has 2 differences in it, but I actually didn't have to click on the STRIPE itself, I had to click on the EDGE of the stripe. Also I actually completed one level without using hints and fairly quickly, and still got no bonus. I pretty much got fed up with this from the first level... Music is weird as hell.
Unit AI's definitely have the dumb. They get stuck where normally they SHOULD be able to move. I have someone cutting trees for lumber, but then he gets stuck, but doesn't use the way that's OPEN. And if I try cutting the trees from the other side, the trees never get cut... Yeah...
I wish there was some Amethyst showing up.. I can't upgrade my blade a second time. Also better regen rate, or small health power ups that enemies randomly drop. I died and had about 20 Mythril gems =/
