The primary spice to this modpack is the Matcha Flavored data and resource pack by Klei Wright. The rest of the pack is small QOL mods such as JEI, WTHIT, vertical slabs, lanterns on walls, a biome compass, teleport pylons, and inventory sorting/quick stack. Should be fairly lightweight. Linked below is more information as to what Matcha Flavored adds/subtracts from typical gameplay.
