I have a lot of thoughts about this game. I have played Progress Knight (the original), Progress Knight 2, and Progress Knight Reborn. I personally enjoyed Progress Knight 2 the most due to the extended progress, and I would expect this game to follow suit, being an extension of that game.
However, I have several main issues: Firstly, the progression is far too automated in the beginning. It would be significantly better if everything being automated was through upgrades rather than being already automatic. (For example, you might be able to spend evil perk points to automate individual skills permanently, or have a bar like the other skills that upgrades with diminishing returns, but is kept on evil/enlightenment.)
Next is Faint Hope. It genuinely drags the game to a halt, and kills my motivation to play it. I was genuinely enjoying the game somewhat at the 15-400k essence point, as I could reset whenever I needed to, but Faint Hope just makes the game such a slog. It makes it so you can only actually make progress a few times per day, and it's such a horrible timewall "feature" to put in a game like Progress Knight.
I do have some positive things to say, though. The automation is obviously bad when it's automating the MAIN PROGRESSION, but once you're at the good part of enlightenment, where you reset frequently, it is beneficial. That is definitely one thing the original was missing, it was just implemented too early in progression in this one.
Next, evil perk points are a really beneficial QoL feature, and while I think the celestial unlock time upgrade should be moved to be in the enlightenment stage, I think they're a beneficial feature to the gameplay.
Challenges are also a nice feature, and there's even some strategy with selecting high happiness jobs and items and pausing the game before you end the happiness challenge.
(If you, for some reason, are reading all of this, thank you for putting thought to my ramblings. I like Progress Knight, and almost all its forks, but I just can't stand a lot of the parts of this game.)
The inactive nature of the game also cuts down on the slog of certain points in Progress Knight 2, but there are better ways of doing that than automating everything far before you're done with it in the progression.
Ultimately, I cannot recommend you play this game past Faint Hope. Which is where almost all the new content is. Should I ever somehow learn to code, I might make my own fork which fixes the issues I have with this game.
