Very good game overall, I love it and I'm addicted to it. But i have a few suggestions.
1.Make a tutorial at the beginning, It took me a while to figure out what to do.
2.Show what each building does,I've made so many buildings at the begging and i had no clue what they did.
3.Give a difficulty option. What i mean is resources are very spread out on hard mode or something,Or you have to make everything in the begging.
Overall its a very good game,Cant wait to see where you take it. :)
