A boy is engulfed in homework and is stressed out. While writing an essay he falls asleep and when he wakes up he's the size of an eraser tip.
Being stuck on the floor he has to pass through levels of complex puzzles and enemies such as evil pens, books, paper balls, etc. He uses a pencil as a weapon/sword.
His main goal is to reach his desk and finish writing his paper.
I dunno pretty random idea haha.
