As an AI language model, I can provide you with a JavaScript-based game template that meets your requirements. Please note that this template provides a basic structure for the game and can be further expanded and customized according to your specific game design.
Here's an example of a game called "Escape the House":
Escape the House
This template consists of a canvas element where the game will be displayed. The player (represented by a blue rectangle) can be moved left and right using the arrow keys on a smartphone. You can further enhance the game by adding obstacles, enemies, scoring mechanism, and other game features based on your requirements.
Remember to save the code above as an HTML file (e.g., escape_game.html) and run it in a web browser to play the game.
