I've used kronbits.itch.io/pixatool and codemanu.itch.io/minifx, but they cost money. There's also codemanu.itch.io/spritemancer, which has more features.

I use this. It offers numerous options for various types of dithering, and you can set any number of color limits. (it's free) www.softpedia.com/get/Multimed...

Damn dude. I hope you didn't lose everything.

Bro… just trust.

I would like to add that after rending these I realized that I could do a better compositing node setup that looks closer to the game. Here are two renders using the old comp setting vs the new one ( The new comp still needs a lil bit of work but it's a major improvement )

lol blender my beloved

Does random obj work?

Is it geo particle?
