This is the game written with Vanilla JS.
Dot appears in random place on the page. When user clicks the dot, it disseaprs, one point is added to the score and new dot appears. The more dots in the row are clicked, the faster they fall. Once dot falls to the bottom, score and dot's speed resets.
Toggle in the top right corner switches the game to the hardcode mode. The only difference between normal mode and hardcore mode is that missclick resets the game.
