This is a pretty absurd game. Generally it's just average, or slightly below, but there's some things of interest to talk about.

The biggest selling point apparently is that these guys Psykosonik did the OST, but it's just okay and reuses songs very often. For example, the opening theme is also used for stage 3, 6, the final boss, and the credits. Also, the entire soundtrack is different in the original Japanese release. And the character names, and the story, and even the title (Sword Maniac). The English localization can pretty much be summed up as insane 90s futuristic bullshit, and I have no idea what the original is about.

Gameplay doesn't change any, though. The stages are okay, but the bosses switch to this 1v1 fighting style and they are all ABSURDLY difficult. They all work about the same, but I never really got down a strategy because they always block a grand majority of attacks and it seems random when they don't. I ended up just abusing save states at each one until I was past them.

Other than those things though, there's not really much to say. Weird ass game all in all.
