Protection of the Kingdom - TD

You are the defender of the kingdom. Hordes of monsters are threatening peaceful lands, and only you can stop them. You must place powerful towers along the road to prevent monsters from passing through.
There are many types of towers at your disposal. Each of them has unique abilities and can be upgraded. Here are some of them::
Arrow Tower-fires arrows at monsters that are approaching the kingdom.
Fire Tower-Fires fireballs that set enemies on fire.
Ice Tower-freezes monsters, slowing down their movement.
Electric Tower-releases bolts of electricity, stunning enemies.
You can upgrade your towers to make them more powerful and efficient. For example, you can increase their firing range, attack speed, or damage. You can also add additional abilities, such as the ability to shoot multiple targets simultaneously or create defensive barriers.
