What is Ultimate Summer about?

You come to the island and meet a long-nosed monkey and a penguin, who are reparing a soul-washing machine. Your task is to defend the device aganist horde of incoming monsters. Simple rules: If you kill the monsters – you win. If monsters destroy the washing machine – you lose.
To achive your goal you may use various weapons. The arsenal is growing every day. Ultimately, there are 10 weapons, 8 traps, and 8 towers to choose from. To buy the equipment, you have to gather enough materials which you get from destroing the environment. Be quick or be dead. Your enemies won't be waiting for the invitation.

Although all this may seem too simple, many opponents have special skills, such as increasing movement speed or strength. As the game progresses, the opponents will come from more and more directions and there will be more and more monsters. Of course, the variety of enemies is also an obstacle. Opponents come from different areas of the universe - including Hell and Purgatory - which is associated with their unique abilities. However, all the monsters have a common goal: to destroy the washing machine.
There are 14 levels (14 days) available in the game. Each subsequent one with a different arsenal and different opponents.
