How the player moves between screens — usually by clicking buttons.
Flowchart
A diagram using boxes and arrows to show the order of things.
Scene
In Unity, each screen is called a Scene — like a page in a book.
When you open a game, you don't jump straight into playing. There is an ORDER:
1. Title Screen → the first thing the player sees.
2. How to Play (optional) → teaches the player the controls.
3. Gameplay → the player actually plays the game.
4. Game Over → the game ends (win or lose).
Back to 1. Title Screen → the player can start again.
Buttons connect the screens:
The Play button goes to Gameplay.
The Try Again button goes back to Gameplay.
The Main Menu button goes to the Title Screen.
In Unity, other students use SceneManager code to change screens. We will plan the flow visually using a flowchart!
Open a game you like (on your phone or computer). Count how many screens you go through before you actually start playing.
I can describe the order of screens in a game.
2 Draw a Game Flow Diagram
A flow diagram shows every screen in your game and how the player gets from one to the next. Draw boxes for each screen, then draw arrows between them.
Draw 5 boxes, one for each screen: Title Screen, How to Play, Gameplay, Pause, Game Over.
Draw arrows between them showing what button leads where.
Here are the connections to draw:
Title Screen → GameplayPlayer clicks the "Play" button.
Title Screen → How to PlayPlayer clicks the "How to Play" button.
How to Play → Title ScreenPlayer clicks the "Back" button.
Gameplay → PausePlayer presses the Escape key.
Pause → GameplayPlayer clicks the "Resume" button.
Pause → Title ScreenPlayer clicks the "Main Menu" button.
Gameplay → Game OverThe player dies (loses all lives).
Game Over → GameplayPlayer clicks the "Try Again" button.
Game Over → Title ScreenPlayer clicks the "Main Menu" button.
My Game Flow Diagram
Draw your flow diagram here (or on paper). Use boxes for screens and arrows for connections. Label each arrow with the button name.

My flow diagram shows at least 4 screens connected by arrows.
3 Create a Flowchart in Canva
Now let's make a neat, digital version of your flow diagram in Canva.
Open Canva and click Create a design.
Choose Custom size: 1920 x 1080 px.
Search Elements for "rectangle"Add 5 rounded rectangles — each one represents a screen in your game.
Label each rectangle:"TITLE SCREEN", "HOW TO PLAY", "GAMEPLAY", "PAUSE", "GAME OVER"
Colour-code them:Title = blue, How to Play = purple, Gameplay = green, Pause = amber/yellow, Game Over = red.
Add arrows between them:Search "arrow" in Elements and place arrows showing the flow between screens.
Label each arrow with the button name:"Play", "Back", "Resume", "Try Again", "Main Menu", "Escape key"
Arrange neatly:Title Screen at the top, Gameplay in the centre, Game Over at the bottom.
Rename your design:"L15 - Game Flow - [Your Name]"
If you can't find arrows, try searching "line" in Elements. You can add arrowheads by clicking on the line and choosing the arrow style in the toolbar.
My flowchart shows all 5 screens connected with labelled arrows.
4 Design a How to Play Screen
This is a new game screen — the 4th one you have made! (You created Title, Gameplay, and Game Over screens in L13.)
In Canva, click Create a design → Custom size: 1920 x 1080 px.
Add a heading: "HOW TO PLAY"Make it big and clear at the top of the screen.
Add control instructions with icons:Search for "arrow keys" or "keyboard" in Elements to find icon images.
Include these instructions on your screen:
Arrow Keys or WASD = Move (search "arrow keys" or "keyboard" in Elements)
Space = Jump (search "space bar" in Elements)
Collect coins = +10 points (use your coin image from L10)
Avoid enemies = lose a life (use your enemy image from L04)
Reach the finish = you win!
Add a "BACK" button at the bottomThis button would take the player back to the Title Screen.
Rename your design:"L15 - How to Play Screen - [Your Name]"
Keep it simple and clear — a brand new player should understand everything in 10 seconds!
My How to Play screen clearly explains controls and the goal.
