Almost all of the blocks have been re-textured to look like the sprites used on 8-bit video games, most of the sprites are from games such as Super Mario Bros And Zelda but have all been modified to fit accordingly with the minecraft blocks some of the blocks however are the same but have been redesigned to make the 8-bit.
Currently Almost all the blocks have been re-textured I just need to finish the items and the Gui displays, and The mob textures then I will pot an update including them as well!
