Another very entertaining Flash game is Desktop Tower Defense. The gameplay is similar to the game Flash Element TD that the webmaster introduced last time, mainly using different turrets to defend against enemy invasions. The enemies move forward from left to right, and if they reach the right side 20 times, it's game over. To block the enemies, players must quickly build some cannons. Enemies will automatically find a detour when they encounter a cannon, so you can arrange the cannons into a maze. However, you cannot seal off the exit of the maze. You will receive a certain amount of coins and score rewards for eliminating enemies, which can be used to purchase different types of turrets.
