I'm not really impressed. It feels less like a tribute, and more like a rom hack of Ninja Gaiden 2. My character moves really stiff in air, and I can't attack while mounted on a wall. I only mention that last thing, because it just seems like kind of a necessary feature in a 2d hack and slash with wall jumps.
The pixel art looks nice, but the borrowed music is really distracting.
Overall, it's not bad, but it's just not very original.
