Sure! Here's a simple game implemented as a single HTML file, using JavaScript and enclosed in script tags. The game is called "Merge Game" and can be played on a smartphone. Pictograms are used to represent the game elements.
In this game, you have two objects represented by pictograms (`pictogram1` and `pictogram2`) initially placed at different positions on the canvas (`object1` and `object2`). The goal is to merge these objects by moving them towards each other. When the objects collide, they merge into one object (`object1`) at the average position of the two objects. The score is incremented by 1 each time a merge occurs.
Note: Replace "emozi_rabbit.png" and "emozi_apple.png" with the actual paths to your pictogram images.
