Pumpkin Jack is a 3D action-platformer starring a mischievous pumpkin-headed jester summoned by the Devil to sow chaos in a world under threat from a good wizard. Players hack through enemies and leap across gothic, autumnal environments.

Combat mixes melee weapons with light puzzle-solving and platforming sequences, including stretches where Jack transforms into other forms to fit the challenge at hand. Its Halloween-inspired art style runs through every level.
