Your stuck inside an empty classroom with your only goal to escape. You start with a piece of paper with a question on it, banana plus apple. To figure this question out, you can press the yellow arrows to look around you and find clues to the answer. To choose which number you think is the answer, you can use your number keys to cycle through the different numbers with yellow squares around them. You also (obviously) have to click on the right code to escape the classroom. But beware, if you get the wrong answer you will be attacked by a monster known as DoodleCreep. While you were in the classroom you were bored, and drew a doodle in the corner of your paper, this doodle then started winking at you as if it was alive, and then everyone disappeared and all the chairs were knocked over.
