Sure! Here's an example of a simple Aquashoot game implemented as a single HTML file using JavaScript:
This code will show a simple game screen with a red ball representing the shooter. You can control the shooter's position by swiping your finger on the smartphone screen. The shooter can move horizontally within the game boundaries.
Note that this code only includes the basic functionality of the game. You can expand it by adding additional game elements, scoring, targets, and shooting functionality using JavaScript.
