Even if this game seems nice, it is bugged as hell and i've never ever seen this many ads in a game. The content is very limited, and when you finish the last building you cannot launch the app anymore since it's in a loading state permanently due to stupid game design. Avoid it.

The ads are how you play and move up. its not an idle clicker. and at level 2 every 20 clicks to move your guys will pop up an ad for Whatsapp over and over until you rage quit or pay to remove the pop up ads to make room for the selectable adsyou need to watch to make any money to make progress in the game. did I mention it has ads? Edit:Holy Jesus, I just went to delete this app and found 4 random game apps had downloaded since I've been playing this and watching the ads. DO NOT DOWNLOAD THIS

Loved it till it ceased to load.. paid for add free and had a total blast for 3 days. Then a few days ago the game wouldn't even get past initial load screen except to occasionally go to an ad and then right back to the load screen. I'm very disappointed
