Beam Ball

Beam Ball is a mouse-only game developed by zyxstand and slashparty. The goal of this game is to touch as many lines as possible without touching a line with the ball of a different color.

Gameplay
In each level, one of the balls follow the player's mouse pointer. There may be other balls with the specific movement pattern depending on the level. When a ball touches a line with the same color, the line disappears and the score goes up by 1. When a ball touches a line with a different color, the game ends.

Each level provides 3 stars. The player must reach a certain score to get each star. Stars unlock more levels, dark world, and story books.

Levels
There are 20 levels in light world, and 20 levels in dark world. Each level of the dark world is the harder version of the corresponding level of the light world. In the light world, every 5 stars unlock 5 new levels. To unlock the dark world, the player must get at least 20 stars.

Busta Line
A red ball follows the mouse, and a blue ball is behind it. All lines are red. Star requirements are 12, 30, 65.

In the dark world, a purple line occasionally appears. Neither ball can touch purple lines.
