Build better defense and claim victory!

Another battle game similar to a game that I had played before -- that's why it's easy for me to get the hang of this one. I noticed that there's an instruction on how to play it but no instruction on how to use weapons and how to aim at enemies!

I'm just guessing here what to control in order to keep the game, but overall I can say that I enjoyed playing this one, I even reached a higher level of the game! So cool!
