Sure! Here's an example of an incremental game implemented as a single HTML file using JavaScript:
Incremental Game
In this game, players can click on a "Click" button to manually increase their score. Additionally, there is an "Auto Increment" button that can be clicked to activate an automatic score increment. The score is displayed on the screen, and it updates in real-time as the player accumulates points.
Please note that this is a basic example, and you can expand upon it by adding additional features, graphics, levels, and upgrades as per your game design.
