Sure! Here's an example implementation of the game you described using HTML and JavaScript:
Adventure Game
Score: 0
Equipment: One-Handed Weapon & Shield
This basic implementation sets up a canvas element where you can control a character using touch controls on a smartphone. Each time the game loop runs, the `update` function is called, which will handle enemy encounters and point calculation. The `draw` function will handle drawing the character on the canvas.
Please note that this is a very basic implementation and you will need to add more functionality to make it a complete game. You can add enemy sprites, implement combat mechanics, and incorporate different equipment choices and upgrades based on the player's points.
Feel free to customize and build upon this example to create your own open-world adventure game using the world of DND theme!
