Jittery Bearing PinBall

This is a re-creation of old-fashioned pachinko pinball.
Easy to play.
All you have to do is to adjust the pushed balls' force.
To adjust the force, push "UP" or "DOWN" button on the screen.
(The balls are automatically shot up as present specifications of pachinko.)
As a bit information for the moment,
There are 5spots you get 3balls and 2spots you get 5balls on the board.
In addition, when your balls fall into the spots labelled “1” or “2”, the robot’s arms open once or twice each.
When your balls enter the robot, you get 7balls.
What is more, if your ball pushes a red button under the robot, a round of “BONUS MODE” starts.
About the “BONUS MODE”,
The robot’s arms continuously open and close until
your balls push the red button over 8times or enter (and sometimes invisibly come out from) the robot over 10balls as the "PRIZES" in a round of the bonus .
The round of the bonus continues each time when the ball pushes the red button.
If you lose all your balls, the game is immediately over.
It'll be the sudden death.
Else if you keep having some balls for 20minutes following the timer of this game, you win and be able to confirm “this time record” of balls you have.
As some additional notes,
1. After the “BONUS MODE”, the game often turns into the spite mode.
2. "RESTART" button is displayed for 3 seconds by double-tapping somewhere on the screen.
(Then the extent of the force to push up the balls is kept.)
I hope that you will enjoy it.
