Had this at a 3.5 at first, but after playing some of the later chapters for each character I had to lower this to a 3 star.

Runs become unbelievably RNG-heavy to the point where some runs die in the first 2 levels because of quality difference in die rolls, and later floors often turn into a rage-inducing slog as you watch the enemy roll multiples freezes, blinds, shocks, poison, curses and what not multiple times in a row with one fight with bad RNG potentially, if not probably, dooming the entire run.

The game wants you to build for every encounter but then almost never actually gives you the tools to do so. There are some good idea's here and there is fun to be had in the earlier levels, but a game in which you lose an entire run because of 1 fight with bad RNG just kills my drive to play it after a while.
