About Sleep Attack
Sleep Attack is a tower defense game where you shape the battlefield and decide which routes invading enemies take. Build and place turrets, then rotate the battlefield to redirect enemies through your defenses. Multiple routes need to be controlled.
Plan your defenses
Choose where to place each tower and how far to upgrade it. The nine tower types have different strengths and weaknesses, and you can use spells when a battle becomes difficult. By changing enemy routes, you can steer them past towers to slow, divert and damage them.
Worlds and enemies
The game includes six dream worlds with levels to complete, 17 enemies with different abilities and massive bosses with their own attacks and abilities. Enemies range from the speedy Boardog to the gargantuan Ghost. The PC version also has improved visuals and gameplay changes.
