OpenEye

Adds a bunch of small tweaks to the game that are all aimed at increasing the difficulty of the first few days. You cannot punch trees; you must turn saplings into sticks, and sticks into a damaged wooden axe. All stone tools require smoothstone instead of cobblestone. Furnace requires one coal in center to craft (so you may not get a furnace or stone tools on your first day; try making wooden tools and finding food first). You cannot gather dirt, grass, sand, clay, or gravel by hand (you can still break them by hand, but need a shovel to harvest the block). Sleeping in a bed will drain your hunger down and also gives you the rotten flesh hunger effect.
