Properly calculated actions will help to avoid a ball colliding with a beam that has not reached the edge of the field. Otherwise, the player will lose one life. The main goal of the game can be considered the ability of the player to hold out on the field for the maximum time.
Simple gameplay in SCALE seems only at first glance, because it is quite difficult to correctly calculate the trajectory of a ball falling and in time to substitute the appropriate block.
Between levels, only the shade of the playing field and the complexity of the game change. In some cases, blocks unexpectedly change their direction. After changing the level, the ball can change its flight path in a random direction.
A player can independently change the color of the playing field, if for some reason he does not like him. The complexity of the levels is determined by the trajectory of the ball and the speed of flight.
