In the above code, the game is implemented as a single HTML file using JavaScript and pictograms. The player (represented by a pictogram) needs to run away from the moving nextbots (also represented by pictograms). The player can use the arrow keys or WASD keys to move and avoid colliding with the nextbots. The player can shoot the nextbots by colliding with them, and their score increases for each successful collision. If the player collides with a nextbot, the game ends and the score is displayed. The game can be played on a smartphone by interacting with the on-screen controls.
Please note that the pictograms referenced in the code (`emozi_all/player.png` and `emozi_apple.png`) should be replaced with actual image files of the desired pictograms.
