GuardGrave is a single-screen action game that borrows elements of Burger Time and other arcade classics. In each level, players must navigate a series of ladders and floors while attempting to close every coffin on the screen. Hammering the lid of a coffin several times will cause it to drop down one level, so you'll often need to knock a lid down several times before it reaches the bottom of the coffin. Meanwhile, a variety of enemies give chase, so players will have to think quickly in order to find safe routes to each coffin lid.
