Sure! Here's an example of a murder mystery game implemented as a single HTML file, using JavaScript and pictograms:
Murder Mystery Game
In this game, you start by talking to the suspects (Olimar, Louie, and A Blue Pikmin) to find out who committed the murder. The guilty suspect changes every round, and you have to keep talking to the suspects until you find the guilty one.
Please note that you may need to replace "emozi_all/pictogram.png" with an actual image file containing pictograms relevant to your game. Additionally, you can customize the game further by adding more complex gameplay mechanics, clues, or character interactions.
