Protect The Wither!

In this fun minigame, your goal is to protect the wither for as long as you can from iron golems. The setting is in a small forest and iron golems appear from each corner of the forest. The Wither is in the middle and you have to protect him. The Wither has 65 HP while the iron golems only have 20 HP. You are invincible and it is your job to protect the Wither. The longer you protect the Wither, you get more experience points. If you get enough experience points, you can buy upgrades to help you protect the Wither.
