Nintendo tough difficulty with a time limit. Controls are pretty much your standard side-scrolling beat em up. Since it's not derived from an arcade trying to eat your quarters, the game is somewhat generous in giving you a handful of lives to roll with. Enemies attack in a pattern, with the timing somewhat predictable. A cool move that Jake can do is drop a bunch of nades and watch them explode to anyone still on the ground (people in mid-air don't get hurt).
