Hi, I'm making Minecraft in unity, my main goal is to try to capture the good old days of Minecraft, please consider installing my game its free!(you can also donate, that would support me a lot!) I'm working hard every week to push out new updates, all i want is advice https://clickstudios.itch.io/minecraft-unity-edition thank you :) 
Yup, seconding this. It’s 100% legal to make a game with the same basic mechanics if you don’t use the same name, textures, specific character designs, etc–all the trademarked & copyrighted bits–but if you do you can expect a Cease & Desist if the game ever gets big.
(also not a lawyer, the above is not legal advice, if you have legal concerns contact a professional to be sure)
