The goal of this pack is to give minecraft a more simplistic look and feel. Some minor details are also "fixed" such as ores and metals. Feel free to use optifine to get access to things like connected glass and metals as well as some "rename textures" like large swords and ruby/emerald pickaxes,swords and armor. To do this just rename diamond tools in an anvil. Optifine also adds connected grass,bookselfs and some other minor changes.
