Late for School Game tutorial: timer and power-ups

Note the purple, red and silver circles in the picture below. (They are two pictures in a collage to make one).

• The icon circled in red is a timer.
• The icon circled in purple is a power-up.
• The icon in silver disappears when your time is used up.

To purchase more time, tap on the icon in purple. Each purchase(tap) is a second.

This game allows credit which explains the negative number in the purple circle.

If you have not purchased any timer in the power-up store then you'd have negative timer.

You get one second credit at the start of each game.


A video would be posted for better understanding.
