Requires >lunacy to do anything (obviously)
Very recommended to use alongside resource packs to bridge the gap in 1.13+ textures, my personal recommendation being Programmer Plus
(also , this pack uses the copper, tinted glass, and bundle textures from Programmer Plus, which makes it significantly more fitting to use that pack alongside this and default programmer textures.)
Project >lunacy is a mod based around old nostalgic versions and their mods, but something just isn't right about it. That's right, it's the dreaded...JAPPA textures! Something you simply cannot have for this experience...
So this mod aims to fix that!
Before: (lame , modern-esq styled)
After: (cool, better style)
