In this action packed addicting arcade, you act as a crazed professor to test his collection of cloned heads of humans and creatures for their physical abilities in a secret experimental lab, HullSkull inc. Now who said that heads are only used for their intelligence? The challenges you will face are various nasty enemies and obstacles on a dynamic platform like piercing spikes, bombarding turrets, falling asteroids, etc. Not to mention the dynamic platform transitioning in and out with time, giving the danger of your head falling overboard.
