It's fine, until you hit a progression wall that forces you to buy MTX so you could get equipment to overcome the said wall. Sure you could grind to not spend a single cent, but it's designed in such a way that you could complete all FromSoft souls games at least once in the time you will spend on the grind for LET IT DIE.
Otherwise, it's an ok souls clone with SUDA51 quirks and twists.
If offline verion will have progression walls removed, then it'll be great.
P.S. Do not even think of playing LET IT DIE Inferno. It's SNCA extraction slop that had zero involvement from SUDA. In fact, developers, Supertrick Games, aren't even connected to SUDA anymore because Grasshopper Manufacture is owned by NetEase while Supertrick decided to stay with GungHo.
