Use Scratch to make an interactive game

Open Scratch and start a new project by clicking "Create" so you have a blank game to build.

Remove the default cat sprite if you don't want it by selecting it and clicking the delete icon.

Add a player sprite from the Scratch library or paint your own so you have something to control.

Add an enemy or target sprite from the library so the player has something to interact with.

Make a Score variable by clicking "Variables" then "Make a Variable" and name it "Score" so you can track points.

Add code to the player sprite so arrow keys move it using "when green flag clicked" then a "forever" block with "if key pressed" blocks that change x and y.

Add code to the enemy sprite so it moves by using "when green flag clicked" then "forever" and a "glide to x y" or "go to random position" block to make it move.

Program collision detection on the player sprite by adding a script that says "if touching [enemy] then change Score by 1 and play sound" so points increase when they touch.

At the start of the game set Score to 0 with a "when green flag clicked" and "set Score to 0" block so scoring begins fresh each time.

Create a Level variable and add code to increase Level when Score reaches a target (for example change Level by 1 when Score = 5) so the game gets harder.

Make the game harder when Level changes by adding scripts that increase enemy speed or add another enemy when Level goes up.

Add a win condition by making code that checks "if Level = 3 then broadcast 'You Win' and stop other scripts" so the game ends with a victory.

Click the green flag to playtest your game and note any changes to make controls smoother or collisions fairer.

Tweak sprites speeds sounds and positions until the game feels fun and fair for you.

Share your finished game on DIY.org so other kids can see and try your interactive Scratch game.
