"PARTICLES" game escaping from a red ball that bounces off the screen

It is a game that runs so as not to hit a red ball that bounces off the screen. As time passes, the number of red balls on the screen increases and the difficulty level increases.

Access is from the following.

Initially we start with three red balls. Use mouse to move.


Next are four. This area is still easy.


Five. It has become interesting.

Seven pieces are difficult to avoid, as the orbits change as they hit the walls and the balls hit each other.


Seven to eight are quite painful.


I intended to run for a long time, 143 seconds. There were 8 balls.
