Abula Tower Defense

Defend from absorbing the army of darkness, consisting of walking dead, dragons and other evil spirits with magical abilities in the game Abula Tower Defense.
You are also not one and form your army at its discretion. However, keep in mind:

• your army consists of peasants, knights and mages that control different elements
• you have a catapult and springald
• at the beginning of each level you get a small amount of money
• for the available money, you can hire new units or to improve the old (which is cheaper)
• at each level you will attack 15 times
• you can without losing skip 19 foes, but 20 will lead to defeat
• for the destruction of the enemy you get a reward
• the last level will bring a meeting with the boss, which is a powerful all
• and - creating a squad, keep in mind the characteristics of their soldiers (for example, a knight and a peasant can't do anything with dragons).
