Sure! Here's a simple implementation of a platformer game where you play as a square trying to escape from circles. The game will be playable on a smartphone and will use pictograms for the visuals.
To play the game, tap on the screen to make the square jump and avoid colliding with the circles. The objective is to reach the end of the level without being caught by any circles.
Note: This is a simplified implementation aiming to show the basic mechanics of the game. You can further enhance it by adding more levels, scoring, sound effects, and other gameplay elements as per your requirements.
