So far I've enjoyed my big armor, high stance axe, heavy use of ranged weapons, and magic/spirit build.
People say this is a mix of Ninja Gaiden (3d) and Dark Souls, personally it feels more like the Way of the Samurai series (3 and 4 are on Steam, recommend giving them a shot if they're sale). All the Nippon wanking, some clunky animations that give it a bargain bin PS2-game feel, dumb outfits, tone that's all over the place, and fights that either go really well and really slow, or really bad and really fast.
Personally I think the gameplay isn't that polished, it's actually a bit lacking. Most bosses you're just fucked if you try to play it like Dark Souls and just guard/dodge while staying near them. You're better off just hanging back, baiting them to do one of the attacks that leave them vulnerable for a while, then getting one or two hits in, then backing away again. Also fighting multiple enemies at once is a pain. The balance is way off too, the game is at it's hardest during the beginning.
Tip 1: Weight/move breakpoints seem to be 30% and 70%. But since there are so few i-frames, and you'll get hit by some bullshit anyway, 70% for heavier armor and "poise" is just generally better.
Tip 2: Even if you don't use certain weapons, get all their skills that don't say "Command: [X to something]". They're passive bonuses that work on every weapon. For example, getting Ki back from dodging is just amazing. EDIT: I fucked up, that example is a normal skill.
Tip 3: Don't spend money on anything early, you'll need it later.
Tip 4: Get the Deus Vult armor at the beginning and you'll get to use it (or make another gear look like it) after the first mission.
