Before entering the game and defending your fortress, you will be taken to a screen with your properties and skills. Here, you will be able to upgrade your abilities to prepare yourself for the onslaught of creatures. You can choose to upgrade your strength and agility or purchase new weapons and magic stones! Once you are set and ready to take on your attackers, enter the game. Click on the screen at the location you want to launch your arrows. At the bottom right corner, you will see the skills you have in your arsenal. You can click here to unleash your skill whenever you please. At the bottom left corner, you will see 2 bars. The red bar is the life of your wall. Make sure this stays up, or it's game over! The blue bar is your Mana. Keep this up if you want to continue using your magic! Now that you know the basics, go perfect your skills and defend your fortress!
