Sure! Here's a simple fighting game implemented as a single HTML file using JavaScript:
Fighting Game
Select your character:
👦
👧
Select opponent:
👹
👽
This game allows you to select a player character and an opponent character using pictograms. Once the characters are selected, you can click the "Start Fight" button to begin the fight. The console log will show the actions performed in the fight.
Note: This is a very basic implementation of a fighting game and does not include any actual gameplay mechanics or visual representation of a fight. It is just a demonstration of how the game flow can be implemented using JavaScript and HTML.
