Why do I still remember so many things about Minecraft?

I recently played the game Minecraft again. And I surpisingly still knew the do's and don'ts on the first night. I remembered how to craft a lot of things and felt like it wasn't fun anymore, because I knew it already. The first time I played Minecraft ever, I was really bad at it and didn't know what to do and how to survive the first days. But eventhough I didn't play the game for so long, I still know how to play it. As if the memory is permanent in my head. Why is this happened and how to not have this? (If that's possible)
