How do you make a platform game in scratch?

To make a platform game in Scratch, start by creating a new project and designing your sprites, including the player character, platforms, and background. Use the "when [flag] clicked" block to set up the game environment and initialize the character's position. Implement movement controls using keyboard input (e.g., "when right arrow pressed" to move right) and add gravity by continuously changing the character's vertical position. Finally, create obstacles, collectibles, and win/lose conditions to enhance gameplay.
