The rule is simple.
Red and blue stars will come raining when you start the game.
Please be the same color as the tile by tapping the star.
Score is added if star and tiles are the same,
If a color is different, one POW gauge will decrease.
POW gauge will be recovered if the tap of the
heart mark which appears occasionally is carried out.
It is game over when a POW gauge is lost.
Now, what point can you take?
