Running game ~I don't study!~

My mom told me not to play games until I finished studying. .
No, it's fine if you don't find out!!
Let's play the game secretly!
A boy runs by tapping the smartphone in the game.
There is a time limit, so let's hurry to the goal!
However, be careful when the teacher passes on the screen.
If you tap while the teacher is around, it's game over!
The score of this game is how many times you can reach the goal.
However, teachers are not the only ones to watch out for!
My mom sometimes comes to my room to see if I'm studying properly.
At that time, let's hide the game with a notebook and let it pass.

Now, how far can you get your score by slipping past the teacher and mom!!
