Neon Switch

In the neon world appeared unknown figures, consisting of several colors.
They threaten to capture all the neon space, expelling local civilians.
The aggressors have already lined up and set a condition: if they are fed to the dump with delicious multi-colored curly delicacies, they will leave without causing harm.
I had to agree to their ultimatum.
You will help the world of neon lights escape from occupation in the Neon Switch.
To do this, you must constantly monitor the gluttons and switch them in accordance with the color of the figure that falls over.
Otherwise, the contract is canceled and the war begins.
