Cephalopoid grabs your eye immediately with its quarapusian shape, but it conceals even greater wonders in its gameplay. Each of its "tentacles" contains either a floorguard, gauss, or floorguard and gauss, all guarding different switches; its "head" serves as the exit shaft; gold is placed strategically so as to appear easy, but in fact increasing the difficulty noticeably. Each one of the "tentacles" is its own separate area, and contain varied levels of difficulty, which will cause you to begin carefully plotting your route of attack, so as to hit the harder spots first.
That's when you realize Nexx has crafted an utterly addicting masterpiece.
