It is time for summer vacations and you got the idea of going to the park where you can sit and relax but after you reached the park you were very surprised to see that there were no other human beings in the park. Everywhere you turned your head you could only see pets. It did not take you long to realize that these pets were here for their summer break. The exit from the place is locked and the key is kept inside the house that you can see in the park. Obtaining the key and exiting from the park has to be your main goal but it will not be easy.
