Best place to learn from zero?

I'm really into S& Box. I think this is amazing. For the time being I'm busy playing all of the creations and giving every one I play a fair shot, chance, rating and reviewing.
 I aspire to create a game of my own one day. All of you creators out there would know the best place to start or maybe using your expert hindsight abilities could point me in the direction. Starting from absolutely zero knowledge. Maybe a Youtuber or possibly yourself ? Who knows. 

I did manage to create a room with a chessboard all the pieces walls/floors wrapped with a skin. A ghost sprite in the corner that plays music. 

That's about the extent of what I have done in creation. 
It Feels like it's not much. The passion is here. just to give
an Idea of where I'm at.
