This game runs directly in your browser. Theoretically, as long as you have a web browser, you can play it. Just note that you may need to adjust your screen resolution for the best experience.
If you are on a mobile phone, you might need some external apps to open it. If you are on a PC, you can right-click the file, choose 'Open with', and select your local web browser. Google Chrome is highly recommended—I used it as the base for development, so if you have it, please prioritize using it.
