Overview

This version mostly overhauls existing content, and changes many mechanics to make it closer to the general canon.

General

Removed normal portals, you can now travel to the Backrooms by crafting a portal block, suffocating, or waiting ~30 minutes :)
Overhauled Level 0 generation, now, the world goes only up to layer 16, and there is wiring on the top of the level.
You can escape by locating random portals scattered throughout the level.
Added Spanish & Russian translations.
Added achievements.
The entity's speed has been adjusted slightly.
The chests now contain more varied loot.
Many other changes I may have forgotten.
