Sure, here's a simple game implementation in a single HTML file using JavaScript, enclosed in script tags:
Score: 0
Tap on the target!
In this game, the player needs to tap on the target pictogram (
🎯) to score points. The target moves to a random position on every tap, and the player's score increases by 1 with each successful tap. The current score is displayed on the screen.
Note: This game assumes touch input, so it should work well on smartphones.
