Two Balls: Merge Puzzle

The two balls depend on each other, attract each other, and look for a bright end with a faint ray of light.

Try to avoid obstacles coming down by controlling two balls.

The two balls are moved symmetrically with each other.
You should show your all ability on concentration, judgement, quick adaptation, patience, timing, and predictive ability.

When you control two balls at the same time, please don’t forget to take care of the other ball that moved inversely.

We hope your brain shows multi-capabilities.
