Inspired by “I have a pen. I have an apple. Uh! Apple – Pen” song, Pen an Apple will help you have many wonderful feelings in the game. With Pen an Apple, all you need is to shoot a pen into the apple and complete each level. However, you can think that it is very simple but it is really quite hard to implement this because the apple will move continuously and quickly. Especially, the game will end immediately if you only need to have a wrong move in Pen an Apple.
