Doors QA

Look at the mental arithmetic problem on the top panel, go through the correct door on the stage, and finish the level within the time limit. When you clear a level, you can advance to the next level and your score will increase rapidly.

- Players who keep running toward the back of the screen can move left and right by dragging.

-The question will be displayed on the top panel, and at the same time the answers will be displayed on 2 to 4 doors on the stage (one correct answer).

- Players can only pass through the correct door, and their score will be added when they pass through.

-If the player hits an incorrect door, he will be bounced backwards and lose time.

・If you reach the goal within the time limit (30 seconds at first), you will clear the level and the remaining time will be added to your score.

・If your score is within the top 20, the high score screen will be displayed, and a list of cleared date, time, level, and score will be displayed.

-One level has multiple stages, and each stage has one set of answer doors.

- Time will be added if you get a potion that is randomly falling on the stage.

- There are 6 types of potions with different colors, and the time added to each one is different.

- As you clear the levels, the number of stages will increase and it will become difficult to clear.

・If you cannot clear the game within the time, it will be "game over". (If your score is within the top 20, the high score screen will be displayed)

-Tap the "Trophy" button at the bottom left to display the high score screen.

-Tap the "Sound" button at the bottom right to turn on/off the sound during the game.

- You can interrupt or end the game by tapping the "X" button on the top right.
