Test your reaction speed and skill as you try to change the color of your character to match the color of your enemies. Once you've changed colors so you match your enemies, hover over them to kill them. Be careful because every enemy that gets past you will make your health bar drop. When your health reaches 0 the level is over. Use upgrades and power-ups to make your monster faster and stronger in order to take out enemies faster and your arrows to move. Have a great time playing City Guardian!
