Great game. However, I do have 2 problems with it:the chiefs and the music. In my opinion, the chiefs are a bit too strong. I simply massed chiefs, with 4-5 beer guys(the ones with the attack buff) and everything went smoothly. As about the music, it sounds really awesome and glorious, so to say, but after a while it does get kind of repetitive, especially since there is a bit of grinding involved. Other than those, I really liked it :)
What I enjoyed doing: at the beginning of a new wave at the part where on the screen was the message with towers+dmg%, i placed the cursor on the eye so that it looked towards me with some sort of ,,dramatic look". I may seem strange but it just felt perfect for the situation...:D
