Buvtack

Restores the old combat system from Minecraft 1.8 and the animations from 1.7.10. Fully configurable

Allows breaking blocks fast/with normal speed while flying or diving under water

Allows you to seamlessly open chests, barrels, and other containers right through mounted signs and item frames. Prevents the struggle of finding that tiny gap just to access your storage

Adds the items and gear the original GoodMC mod made for Minecraft 1.12.2 did
