To make a 2D game that can be embedded using HTML, you can use a game engine such as GameMaker Studio or Construct. Here are the steps to create a game using GameMaker Studio:

1. Install GameMaker Studio: First, download and install GameMaker Studio on your computer.

2. Create a new project: Open GameMaker Studio and create a new project. Choose a 2D project and set the resolution and aspect ratio for your game.

3. Design your game: Use the built-in tools in GameMaker Studio to design your game. You can create levels, add sprites and objects, and program the gameplay mechanics.

4. Test your game: Use the test mode in GameMaker Studio to play and test your game. Make sure everything is working as expected.

5. Export your game: When your game is ready, export it as an HTML5 game. Go to the "File" menu and select "Export." Choose HTML5 as the export format.

6. Embed your game: Once your game is exported, you can embed it on a website using an iframe tag. You can also upload the game files to a web server and share the link.

7. Publish your game: Finally, publish your game so that others can play it. Share the link to your game on social media or other platforms.
