It is a game that defeats the rat that comes out 
from the hole in the upper part of the screen a lot of being touch in 30 seconds. 

When a blue rat is defeated, ten points are added. 
When a red rat is defeated, 50 points are added. 
When they are missed, 10 points are subtracted. 
The bonus score can be gotten every ten combos. 

Let's aim at a high score!
