Sure! Here's a simple fishing game implemented as a single HTML file using JavaScript:
In this game, there is a fishing area represented by a `<div>` element with an id of "fishingArea". When the player clicks on the fishing area, they catch a fish and their score increases by one. The current score is displayed in an alert box.
Please note that this is a very basic implementation and there are no actual pictograms or smartphone-specific features in this code. It can be enhanced further by adding visuals, animations, sound effects, and additional gameplay mechanics as per your requirements.
