Damn the first thing i thought when i looked at it was 'Junji Ito'. Nice job.

yeah, probably e.g. dark cream white, red, brown would fit better, nevertheless, it was just for testing purposes. I may try to reupload it in future

I get the whole message of this but i feel like the gameboy color palette was not a wise choice for this personally... I think maybe a base blue even if at 4 colors would have made it less awkward to look at. Theres nothing wrong with the design just the color palette in my opinion.
