God Has Left Us

I wanted to create a true hardcore experience, and this is what I came up with. It took about two days in total. Here, you'll have to endure a constantly increasing difficulty and your character's weaknesses... It's an unforgettable experience if you can complete the game or survive the hardcore mode and reach the ender dragon.

In short, here's the survival guide:
1.(Gravel, mine its block until flint drops out instead) First of all, urgently get some flint. It can be found under the ice using a creeper explosion (another way is snow, which will cause you to fall into the water and lose, with a 100% chance you won't be able to get out of the water; this method is only works if you've enabled inventory saving). This seems to be the easiest way to get flint. 2. Get sticks from tree leaves.
3. Find a spider; you need thread; grass can't be harvested. Then quickly craft an axe and harvest wood. Once you've harvested enough, burrow underground and immediately upgrade your gear to stone. It's advisable to get wool for a bed, but it's unlikely to work. (use translate)
