First of all thank you for the comment and all your directions. I really appreciate that you like the idea!
I'd like to know what you find difficult to understand in the game, so that I can improve the game and make it easier to play. The cost of buildings is 70 GOLD for everything, I knew it isn't visible, I'll fix it.
I'm not really good at audio effects... could you help me with some quick tips about if it is better to find assets online or create them yourself and how to do it? :)
Thank you!
