Cookie Clicker Game
Score: 0
Upgrade: 1x
In this game, the objective is to click on the cookie to increase your score. The score is displayed at the top, and there is also an upgrade button that can be clicked once you have accumulated enough score (10 points). Upgrading increases the score multiplier, making each click worth more points.
