Frustrating Game

Okay so when I first downloaded this game I was hooked. Now...I've only been able to get so far though and I feel like I'm just going in circles with this game and getting nowhere now! I don't even know how to tell which level I am!!!! I seem to be stuck in a spot where I get impossible requests and my buildings are constantly being destroyed. It's very frustrating to not know where I stand in this game...if the end is in sight or if I'm no where near the end. I don't know what I'm doing wrong or if there are any tricks I just don't know about. If anyone has any suggestions that can help me out here I'd greatly appreciate it! I'm beginning to feel like this is the Diner Dash games where it's just impossible for me to get past a certain point and I have to give up...another game coupon wasted, ya know? I'm getting frustrated with Big Fish and myself because I get hooked on these games thinking I'll really enjoy them and then just wind up being frustrated with them in the end...it's very disappointing and I refuse to admit defeat and give in letting my coupon really go to waste though LOL. <sigh>

Thanks in advance.
