Here's a simple text-based game example that you can play:
Monster Hunter Game
This HTML file defines a simple Monster Hunter game where you can attack the monster, perform special attacks, or heal yourself. The game ends when either the player or monster reaches 0 health. The game is text-based rather than graphic-intensive, but I hope you find it enjoyable!
