Escape The Cheerful Classroom

You are at school and you have stayed behind in class after all your colleagues and teacher left to finish up with some notes. But when you were finally ready to leave, you discovered that you are locked in. Now you have to use your brains to get yourself out of here. Look everywhere for tools that might help you. You can find clues in the trashcan, you can use an eraser to reveal something written underneath some drawings, you can use a sharpener on a pencil and then write something in a notebook and you can find a lot of clues that will help you solve puzzles and reveal new clues or tools. Finally you will have to find the key that will open the door and will get you out. Do you think you are smart enough to succeed? Have an incredible time!
