Sure! Here is a simple example of an HTML game implemented with JavaScript using pictograms for a Roblox obby-style game:
In this example, the game includes a player, obstacles, and a finish line. The player can be controlled by dragging it using touch events on a smartphone. The player's position is constantly checked for collisions with obstacles and the finish line. If a collision occurs with an obstacle, the player's position is reset to the starting point. If the player reaches the finish line, a congratulatory message is displayed.
Please note that for the game to work properly, you would need to replace the `emozi_all/game.png`, `emozi_dog.png`, and `emozi_himawari.png` image URLs with the relevant pictogram images.
