Sure, here's an example of a simple game where you can kill rats by tapping on them with pictograms:
Rat-Killing Game
Score: 0
In this game, the objective is to click on the rats (represented by pictograms) to kill them. Each time you click on a rat, your score will increase, and the rat will be removed from the game. The game ends when all the rats have been killed.
Please note that for the pictograms to display properly, you would need to replace `emozi_all/pictogram.png` with the actual file path or URL pointing to the rat pictogram image.
