Ratings and reviews

I am rather enjoying this app but I do have some constructive criticism to add. A bigger map would be really helpful. I completely understand there are size limitations for a mobile game. But surely there has to be a way to achieve this. Some sort of explanation of what buildings do would help a lot too. For example what does the bridge do? Finally to those who have said this is too hard. Each resource spawner can have 4 roads coming out of it. This will make your life so much easier.

I've played a few times and it seems impossible after a few rounds, because of the wall staying at the same HP when you go to the next wave. Maybe there will be an update to make the game a little less challenging. Thanks to whoever reads this. Edit: I replayed the tutorial and figured out a strategy that I missed!!! Going to add another star!!

Love this game, but I am basically done, can't play any new levels. Idk if it's a bug where my troops can't leave my base or if they've run out of content. Would be 5 stars if I could keep playing
