Rice cake making

This application is a game to make a lot of rice cakes.
A game begins if I tap the left side with a title.

Three icons are displayed during a game in the upper part of the screen.
An icon "mallet", or either "hand" is displayed.
In the case of a mallet, an icon taps the left side of the screen.
In the case of a hand, an icon taps the right side of the screen.
One rice cake is completed when I can tap it definitely.
