Sure! Here's a simple implementation of the game "2D Fruit Slice" using JavaScript and HTML, as a single HTML file:
Score: 0
This implementation creates a canvas element where the game is displayed, and adds touch event listeners to detect finger movements. It uses an array to store the fruits that appear on the screen, and updates their positions every frame. It also checks if a fruit is sliced by touching the bottom of the screen and updates the score accordingly. Finally, it displays the score and handles the game over condition.
Please note that the sound implementation is not included in this code, as it requires additional resources. You can add your own sound implementation using the `playSliceSound` function.
