Very solid Souls experience, too good that I actually plat'ed both version.
1. The combat is the biggest selling point, and the most satisfying part of the game for me. Initially, there were quite a lot of criticism about its combat design logic, I get it, the character was initially underpowered and some design designs were questionable. But once you collected all the quartz to upgrade the skill trees, the combat is a blast. The perfect deflection is such a satisfying mechanical (and this is why I highly prefer Sekiro to Elden Ring as my favorite souls game), the staggering and executing enemies just add different layers of flavor of the combat system. I actually went back to play Dark Souls 1 2 3 and definitely felt the combat is quite simple and so to speak outdated compared to newer entries.
2. Other than combat, the level/map design and exploration is another pillar of fun of the souls game. I think Lies of P did quite well in each individual levels (each chapter) - they used the verticality and alternated interior/exterior well, and the shortcuts indeed have the Souls flavor. However, when it comes to the interconnection of the overworld, the game falls short compared to Miyazaki's masterpieces. Lies of P lacks of grand magnificent landmarks/scenes, which are very signature stuff in FromSoftware's games. And the overworld it more like a central-hub-to-branch-area structure, lacking those mind-blowing interconnection you saw in Dark Souls or Bloodborne.
3. The game's other aspects, as art style, music, graphics, and optimization are all very on par. It is really a remarkable achievement for a studio that only made one Korean MMO before. They really grabbed the essence of what makes a souls game good and added their own flavor as well. I would rate it 8.8/10. Looking forward to the announced DLC and sequel.
