Ok, thanks, what dithering algorithm would you recommend then (I'm using a 4x4 bayer matrix with rounding in the previous image)?
I honestly think you should do research and look at games that were rated high to get a feel for what is popular during these jams because I’ve seen people use all kinds of art styles.
I have not seen a successful game that did something similar to what you are showing. I don’t think the point of the jam it to make a monochromatic game. :) I have seen some dithering (rarely) but it looked much more rough.
