Does anyone remember the old minecraft demo back then?

I feel like I’m the only one who remembers this. When I was young and couldn’t afford to buy Minecraft, I played the demo version. It was basically minecraft but you had 100minutes to play with, but you could re-loads as many games as you wanted. You usually spawned in a plain, and sometimes in a plain/oak forest. I really liked playing this version as a kid, and I was wondering if anyone remembered this as well?
