My friend and I were starting a new world and started adventuring and thought, "Hey! They should add creatures and monsters too this!" So maybe you guys should add some creatures that are friendly that can possibly become pets, creatures that are neutral that just don't want to be bothered with or killed, and monsters that are hostile and can kill others. Which means you need some sort of safety equipment like Armour or weapons you can have. Also maybe make a health bar which would be handy and maybe hunger since you can kill creatures you can probably add some sort of meat to the game. There are some ideas for the game that will make it more interesting and fun! Hope you read this and have a good day!
