Tough Beginnings

Trees no longer give wood when punched. The player has to harvest gravel to get raw flint, and raw flint is of no use until it is sharpened by bashing a stone block, which gives a chance of flint. Failed attempts leave flint shards that combine into a new gravel block. Once flint is in hand, a flint knife can strip fiber from the foliage around the player, and fiber turns into fiber rope, which is needed for a flint axe. Logs are then obtained normally with the flint axe.

Plain wooden planks stop being a direct option for wooden tools. Planks and blocks are carved with a knife held in the main hand, and a fire is started by right clicking with a stick in the main hand, using friction. Fire toughens wood blocks, and tough wood is what the wooden tools are crafted from. Stone no longer drops itself when mined: it drops rocks that combine back into the original block, and the stone tool recipes take the player into the stone age. Every player and the server need a copy of the mod. It is published for Forge and NeoForge for 1.20.1 and 1.21.1, with 1.9.4 as the latest file for both loaders.
