An action platform game that moves between channels [Dr. Degauss]

One day, TV repairman Dr. DeGauss discovers that a customer's TV screen is displaying animated spots, obscuring and distorting the information on the screen. He discovers that these spots are caused by the evil villain Ms. Headroom's hijacking of the signal. If left unchecked, this phenomenon will expose everyone to sensational media. To thwart Ms. Headroom's plot, DeGauss switches between channels, correcting the signal errors.
