The reason I reported this is because of its shape. I was rushed and couldn't provide a proper explanation. When it was formed, I couldn't enter it at all. I closed the world and restarted it and that's what formed. And yes, I knew it was a ravine.
Okay, I tested it. The game needs at least 200M to run. My bad. We can mark this as resolved.
Oops. I just realized I packed it in the Rar5 format.
My bad.
1M is less than 100M. Don't you mean 1G? Correct me if I'm wrong; I read that 100M of ram was enough to run Vanilla Minecraft.
*I know what a ravine is.
