Sure, I can help you create a simple game called "Gorilla Tag" using HTML and JavaScript. Here's an example implementation:
Please note that this implementation uses pictograms as placeholders, so you might want to replace them with appropriate images or game elements as per your requirements. Additionally, the user interaction for controlling the gorilla's movement is not yet implemented and needs to be added based on your desired smartphone operation.
Feel free to modify the code and enhance the game further based on your preferences.
