Sure, here's a simple game implemented as a single HTML file using JavaScript. It's a guessing game where the player needs to identify the pictograms shown. The game is designed for smartphone operation and uses the feature of throwing out cities if the player enters "Budapest" as a response.
Note: Please replace "emozi_rabbit.png" and "emozi_apple.png" with actual image URLs or filenames, and add more pictograms as needed.
