Wooden picks and copper ores

If wooden picks could mine copper ores, the copper tier of tools would have more value and a clearer reason to exist. The player would have a different option for early progression: either follow the usual route by making stone tools, or wait a short time to smelt copper and craft tools that are slightly better than stone. This wouldn’t affect overall progression, but it would make it more flexible and engaging, giving players a meaningful early-game choice instead of a one-way path, while preventing copper tools from sitting aside with no real purpose.
