GOOD STRATEGY YOU SHOULD USE! Focus on ONE tower, in the middle of the path, and upgrade it ONLY! Nothing else needs upgrading if you put the range of the center one at the most. + if you agree!
Guys, I know this game sucks, but it's actually decent if you get the hang of it. You can barely read some of the costs, but who cares? It's a decent idle. I don't care if this is downrated (yes I do) because it's the truth!
