Sure! Here's an example of a simple game similar to Splatoon Splash using JavaScript and pictograms. Just save this code in an HTML file and open it in a web browser on your smartphone to play.
This game creates a canvas element that fills the whole screen on your smartphone. You can control the player's movement by touching the screen and moving your finger around. The player, represented by a blue circle, will follow your touch position. The player is confined within the canvas, and as you move, the canvas will be cleared and updated in the game loop, creating a smooth movement effect.
Feel free to enhance and modify the game according to your preferences!
