Description

Calvin's Wonderland.jar

This modpack is built around the "Wonderland.jar" experience made famous by Calvin. It’s designed to mirror the eerie atmosphere of his series, focusing on a slow-burn horror experience where you are constantly being hunted

What to Expect:

The Hunt: Strange entities like no_one, Fate, and Sorrow will stalk you. They don't just jump-scare; they watch and eventually pull you into the **"Wonderland." ** The Wonderland: A liminal dimension (Backrooms-style) featuring 25 levels and 32 unique entities.

Unpredictable: The pack is extremely random. You might be taken on Day 2 or Day 15—you never know when it's coming.

General explanation of the Modpack

WonderLand.jar is supposed to be slow-burn and it is EXTREMELY random, in some worlds you'll get taken to "wonderland" on 2nd ingame day, in others it'll take 15 ingame days for anything to happen
