This is a demo of a CSS game I developed using "only CSS", no JavaScript or HTML. The game uses animation and transforms that combined make WebKit browsers (Chrome, Brave, Safari, etc.) struggle a little. If you want to check the demo yourself, it may be better to do it on Firefox. If you use WebKit, try to make the screen small, and/or reduce the resolution in the game (instructions in the comments).
