Hey I found this today and it helped me immensely. Seriously thanks

The sound sounds really cool and unique

Love the color palette

Ooo this looks really good

Looks great!

At a certain point, you have to jam everything into a subviewport

Oh woah - really pinging some core memories with that one

Relevant part of the shader code:
void fragment() {
vec4 tex = textureLod(map_texture, UV, 0);
ivec2 map_coord = ivec2(tex.rg * 255.0);
COLOR = texelFetch(colours_texture, map_coord, 0);
COLOR.a = tex.a;
}
