Personally, I remember all my first experiences on all of the different versions of Minecraft I’ve played! (Xbox, PS3, MCPE & PC).
When I first got the PC version, I played a superflat, singleplayer creative and had no idea how to move. I remember specifically seeing slimes, and being annoyed by the sound because I was completely clueless about the controls and settings.
...Ahhh, the memories!
