Hello! I loooove your game! Thank you for such a wonderful, incredible homage to the great CRPGs of yore. May I ask what color palette you used for the game? It almost looks like an EGA palette but not quite? I like the neon aesthetic and I'm a budding pixel artist trying to learn more about the discipline.
No colour palette, really. The game uses black, white, a primary, secondary and darkened secondary all derived from mathematical relationships around the HSV circle. Basically pick a direction on the colour wheel and then look opposite (for the secondary) and then a darker and slightly cooler or darker warmer for the last colour. Hope that helps!
