Tower Defense is a strategy game in which you have to defeat all the enemies that come your way. The game is based on the same genre as the classic Tower Defence games, however, it has several differences. You have to defeat all the enemies before they reach your tower. And instead of your units, you have to place towers.

The towers are the tools you use to defeat the enemies. Every tower has its own characteristics and abilities. You can use these characteristics to defeat all the enemies. 

The gameplay is very simple. You can use the left and right arrow keys to move your towers or use the spacebar to move them. Every tower has its own range, and this range can be increased by upgrading it. 

When you defeat the enemy, you will get money or silver coins. These coins will help you upgrade your towers or buy new ones.
