Ok, absolutely nothing was cut or removed from the game and even if there was something cut that thing was either not working, or it was just a test. And I'm lying, discord is lying, game's own code written by its own developer is lying.
And we should always look at the worst examples of games so we can see KP as a some sort of miracle from god. We should never ever look at the better examples of games because we might see what is missing and what might make KP better. Nope, never do that because it would also harm our little safe space where we worship KP(because it is divine blessing from the god or something like that).
Cool story and nice logic.
And since you've asked so nicely, here is something from dev's own reports. Behold, his reason for level 4's current state:
He's openly admitting level 4 is in this state because otherwise it would be bad for the player

With this logic games with much more content and gameplay mechanics such as elden ring or cities skylines shouldn't exist because they would absolutely overwhelm the player, so they wouldn't work in practice. What a load of bull

Yet here we are, those games are STILL being played by ~20k players
every minute while KP could barely hit 1k players at its all time peak(when it launched on steam). But I know what you are going to say: "d-don't compare Remtairy to such big studios". Well guess what, I compared Remtairy to solo developers that had 0 budget and you still ignored them because you think I'm cherrypicking. There is literally no way of arguing this with you. You are completely single minded about this. You clearly see KP as a miracle and you won't accept anything else no matter what I say.
I'm done here talking about this. You can feel free continue viewing KP as a miracle from god or something.
I'm gonna go play those games where I "absolutely get overwhelmed" by the sheer amount content and gameplay mechanics

instead arguing with some single minded fanboys.
