Sure! Here's an example of a simple game that involves water movements and shading animation in 3D using JavaScript within a single HTML file. Please note that due to the limitations of text-based interface, pictograms may not be feasible. However, I'll be using ASCII art to represent the water movements.
In this game, you'll see a canvas element representing water. The water level starts at 80 and gradually decreases every 100ms to simulate an animation of water level changing over time. Additionally, when you tap on the canvas, the water level increases by 10 units. The water is represented using colored rectangles in a 3D perspective.
Please note that this is just a simple demonstration and can be expanded upon to create a more complex and visually appealing game.
