Sure! Here's an example of a simple platformer game with a square character that can turn on and off. It includes mobile controls and uses pictograms to represent the platforms.
In this game, the player (represented by a red square) can move left, right, up, or down using touch controls on a smartphone. The player can turn on and off, making it visible or invisible. Platforms (represented by black rectangles) are visible at all times. The player must navigate through the platforms to reach certain goals or objectives.
Note: The code provided above is a basic example to demonstrate the concept of the game. You can enhance it further by adding collision detection, additional levels, power-ups, enemies, etc., based on your requirements and preferences.
