Crows that spoil.

Why not make crows so that they spoil your crops and eat them, this to make the game more difficult, since it is (very easy). They can also add that they are peaceful, but if you attack them, they can lynch you collectively. In addition to adding scarecrows, to scare them away from the crops. They can also give crows the quality of giving black feathers. This is optional, you can make a feather hat for winter, since the game is "survival". They rarely give you valuable items if you kill them, since they collect valuable things in real life. In addition, they can be your pet, sporadically, they bring you things ("everything") but each object has a probability from very probable to very unlikely, (almost impossible), such as the best enchanted book or the best sword," months of play." Also, to not make the game too easy, let the crow defend you from the enemy, but with its attacks being one at a time in the long run, since we don't want to corrupt the game to make it extremely easy. But this is optional so you can embody it, you don't have to take my advice literally, make it better to your ideas.
