Hit the 'monster' when they appear! This game is similar to the Whac-a-Mole machine that you can normally find in shopping mall or arcade shop, and believe it or not, it is created by a 10 years old student. I think I only know how to watch TV when I was 10 years old, or maybe read some comic books.
It actually consists of over 80 lines of code! It is not visually appealing but the functionality is there, just need to touch up the graphics a bit and the game will be super cool.
Try it out, and let us know what do you think, and what can be improved! Sow us your highest score too!
