If you haven't read Necromancer before, I suggest you do so. Although Death Song is more of a parallel, most recommend reading Necromancer first.
All of that aside, this game is amazing. The plot tells of a musician struggling to survive in (Spoiler - click to show)the world ruined by the main character in Necromancer.
The writing is emotional, even haunting at times due to the desperation, struggles, and the dismal situation of the time. There are a variety of endings, each with it's own sense of despair. Some are where (Spoiler - click to show)The musician dies alone, humming a tune to himself; The musician plays one last tune before the NECROMANCER, before drifting off, etc.. You can really relate to the character as it is extremely well written, the choices feel logical and every character has a great backstory, defining characteristic, etc. Nearing the end, you feel that death is surrounding you, that you are running away(if you survived) but it is slowly catching up, as if every step you take is closer to doom.
Overall, I would recommend it for anybody who would want an extremely emotional play(Spoiler - click to show)(Don't say anything, but I almost sobbed), another great one from EndMaster. 5/5!
