If the game has jumps, it will require quick reaction from you, and the Jumper game is a purely jumping arcade game in which the green ball must constantly jump, otherwise it will not move forward. The space bar acts as a control button. By clicking on it, you make the ball bounce, while paying attention to what appears in front. In addition to the unevenness of the relief, various shapes in color and size will move towards the ball. They also need to be somehow bypassed, or rather jump, avoiding a collision in the Jumper game. You cannot endlessly jump up or down, the field is limited by rows of sharp spikes from above and below.
