Sure, I can create a simplified version of a game similar to Geometry Dash using JavaScript and pictograms. Here's an example implementation:
In this example, the game starts when the user touches the screen. The player can make the character jump by tapping on the screen. The objective is to avoid colliding with the top or bottom of the screen. If the player collides, a "Game Over" message is displayed, and the game restarts.
Please note that this is a simplified example to illustrate the game concept and may require further development to match the complexity and features of Geometry Dash accurately.
