Sure, here's a simple game implemented as a single HTML file using JavaScript. The game will run in your web browser, including on smartphones. It utilizes pictograms for visuals and allows you to play as a character moving around, avoiding enemies and trying to defeat them using a knife when close.
Make sure to save the pictograms for the player and enemy as `emozi_all/player.png` and `emozi_all/enemy.png` respectively, and place them in the same directory as the HTML file.
To play the game, simply open the HTML file in a web browser, and you'll be able to move around on the game board. Clicking the player icon when close to the enemy will trigger a win, and the enemy will then be repositioned randomly. The enemy will also move to a random position every second to block your path.
