[...] But I really want to see you doing something better! [...] Show me you can do better or stop talking bullshit
See Javis, this is the beauty of critique: you do not have to be as good as the person you are criticising, you merely need to have enough understanding of the subject.
I am not a musician, tho I can still tell if a certain piece of music is poorly made.
The difference is that here many people are very good pixel artists and if given the assignment to do something like this could do as good or better.
To be fair the team making KOF is under a timeschedule which probably is quite tight so more power to them for doing things in a streamlined way which does require minimal back and forth communication to approve stuff since there is a really simple style guide.
The main problem I am having is the high talk they are spouting on their page, which is marketing yes, but total nonsense.
The art in KOF is so streamlined and robotic in execution that there can not be much talk of soul.
Who are u to approve or not something!
This reply was a bit tongue in cheeck and sarcastic, next time I will add some kinda smiley

Of course I am in no place to tell anyone what they should do unless I would be in their team heading the art direction.
That said, I worked on games where we had colourswapping which was quite complex, but that would require extra communication between the coder(s) and the artist(s), which I take there is no time for in such a big streamlined game.
My suggestion to you is not to take everything you read on the internet at 100% face value and not get a knot in your pants if someone attacks something you might be a fan of. It will make your live a lot less stressful.
To the people who said the times estimated are hilarious, have you actually calculated it?
Let's see:
1 working month = 20 days
6.5 month = 6.5 x 20 = 130 days
1 normal working day = 8 hours
130 days = 130 x 8 = 1040 hours
1040 / 500 frames = 2.08 hours per frame.
Roughly 2 hours to clean up frames as big as the ones here from the 3D render to a flatshaded 2D look or to do the gradiation and whatnot pass seems a fair time assessment to me.
