Sure! Here's an example of a simple Splatoon game implemented as a single HTML file using JavaScript and pictograms:
This game is a very basic implementation where you control a player (represented by a green circle) using the arrow keys on your smartphone. The goal is to move the player around the canvas area. The player's movement is handled using keyboard events.
Please note that this is a simplified version, and you can extend the game with additional features such as opponent squids, ink splats, or a scoring system based on the original Splatoon game.
