Sure! Here's an example of a simple game where the player needs to avoid killing their grandpa. It's designed for smartphone operation and uses pictograms. The game is programmed using HTML and JavaScript in a single HTML file enclosed in script tags.
In this game, the objective is to control the player's pictogram (represented by `playerImage`) using touch input on a smartphone to avoid colliding with the grandpa's pictogram (represented by `grandpaImage`). If the player's pictogram collides with the grandpa's pictogram, an alert message is shown indicating that the grandpa has been killed.
Please note that you need to replace the image paths (`emozi_rabbit.png`, `emozi_all/player.png`) with the actual paths to the pictogram images you want to use.
This is just a basic example to demonstrate the game concept. Feel free to modify and enhance it further according to your needs.
