Really nice, but..
I think this game is really nice but there is few things that was just bizarre for me :
First, in the game mode, I think it's not normal that red towers are so efficient. Like in the game I just played, my "biggest" tower was a red one with 575 poeples (by making 13 combos) and I didn't achived to reach 500 poeple with yellow towers!
Also in the game mode, when the number of inhabitants decreased you should not put the minus sign in the sentence because saying that the population decrased by -50 logically means that it increased by 50.
An finally, I you should able us to know how much poeple are in each towers to grow our little city faster.
