@Blaze, the learning curve seems to be medium, not too easy to pick up but not too complicated either. The fact that there is an encyclopedia avaialble is pretty helpful. Plus in the chat most people don't seem to mind helping.
This game get's terribly boring after the 1st couple of missions. I like the addition of the redistribute button and the medal system is neat; all in all 3/5 stars.
Quit whining, the achievment is 10 seconds less than the one that was available when they had this game in the card challenge. Maybe instead of thinking that it relies on luck you can play it more than twice, if your A.D.D. doesn't preclude you from doing so.
I think the trick is to not focus on either side, but to yous your "peripheral vision" to pay attention to both sides at once, it's not complicated, almost Zen like. Great game.
There are different "Harmony" awards. There is one for Symbol Harmony meaning that you have 4 of each symbol and another one for Color Harmony for 4 of each Color, the bonus is different and so are the "power-ups" you get for acheiving them.
The control thing is a big issue, the drag on the eagle makes it very difficult to know if you're even in the playing field or not. It makes the game difficult because of control. That's not really what should make the game difficult... 3/5.
