Tower Defense 2D

Build towers by clicking on a special place with a sign. To move around the level, press and hold the cursor on an empty spot and move it up or down. To use the ability, click on the appropriate button and click where you want to apply it. You can click on an existing tower and upgrade it, sell it, or use the special tower skill (unlocked at the third level of the tower). If you defended your castle from all enemies, you won and the next level will be available to you. If the enemy entered the castle - you lost.
