Sure! Here's an example of a game about a black hole sucking up contestants in BFDI, implemented as a single HTML file:
In this game, the black hole and contestants are represented by pictograms. The black hole will be drawn at the center of the canvas with a given radius. Contestants will be drawn at their respective positions on the canvas. The game continuously checks if any contestant is within the radius of the black hole and removes them from the game if they get sucked in.
Please make sure to replace the `<blackhole.png>` and `<contestant.png>` with the actual image file paths for the black hole and contestant images. Additionally, you can modify the positions and number of contestants as needed in the `contestants` array.
This game is compatible with iPad and mobile devices, as it adapts to the dimensions of the device's screen with the help of the viewport meta tag.
