You can save the above code in an HTML file (e.g., "raft_game.html") and open it with any web browser to play the game. It will prompt you to choose actions (1-4) and inform you about the consequences of each choice. The game ends either when you run out of supplies or after surviving for 100 days.
Note: For pictograms or more complex visual elements, you would need to incorporate additional CSS and possibly image assets. The above code provides a basic text-based implementation of the game as per the requirements specified.
