Sure, here's an example of a simple Zanpakuto game implemented in a single HTML file with JavaScript. The game is played by tapping on pictograms representing Zanpakuto attacks on a smartphone.
In this game, the player can tap on different pictograms representing Zanpakuto attacks (a slash, a stab, a crush, and a blast). Each time a player taps on an attack, the score is incremented by one. You can implement the actual logic for Zanpakuto attacks inside the `attack` function based on the selected type parameter.
Feel free to customize and enhance the game as per your requirements!
