Musashi starts out at night on this long walkway punctuated by several platforms. Along the walkway are robots, and on each platform is an ambush of faster-moving humanoids. The walkway eventually reaches a circular tower, and inside is a grating along the edge that eventually leads to an elevator, which takes Musashi to the roof, where a boss awaits. I don't think it's possible to beat the boss within the demo's time limit, so that's where it ends.
