I think the missiles should cost 500 gunpowder and 300 metal, the lock should also cost metal and not wood, you should improve the clashes, the arrows are very slow And it seems that they are going in other directions, tools and weapons should last longer, wood and bone armor should have more protection, the bullets should not do as much damage, you should reduce the times of the things that are being done or that many things can be done at the same time, the wooden walls should resist twice as much the same with the stone and metal ones, the lamps should not be unlocked, the shotguns should do more damage the same with the revolvers, for the cheaters you should set a speed limit at which the player can go and if he goes over the limit it kicks him off the server and bans him, the same with the height you should set a limit of what a player can jump and if he exceeds that limit, he is expelled from the server and banned
