Sure! Here's an example of a text-based game based on the Death Note concept, implemented as a single HTML file using JavaScript:
This is a simple implementation of the Death Note game using JavaScript within an HTML file. The player is prompted to enter their name, followed by a brief introduction to the game. They are then given a choice between writing a name in the Death Note or closing it. Based on their choice, a random outcome is determined, resulting in different endings.
Note: This implementation is just a starting point and can be further expanded to include more choices, endings, and pictograms based on your preferences.
