Adrian's Cassette Collection
This image was drawn poorly, but who cares.

Hello! What's up?

I was going through some addins on this site, and then I saw Monochrome_95's addin that introduces an idea of Cassettes, and then I though that I could do something similar.

I present to You... Adrian's Cassette Collection!

(Since the addin's size is massive (because of all the tracks that are over two minutes each), here's a Google Drive link:

There are 12 cassettes so far. Each one with unique song.

World of Goo: The Unknown World

Before you continue, The Unknown World is continuing development during, as well as after, is archived. Do not panic!! While I may not be able to upload the new chapters or give updates, everything will be available somewhere. I'll be certain to find a spot where new chapters for The Unknown World can be downloaded from. I'll let you know via my youtube channel


This is an unofficial version of World of Goo 2008

Metal Matter

A chapter goomod made by me, Ravon!

This mod takes place in an industrialized world with unique islands filled with many wacky robots, you decide to explore with your goo ball companions to discover the mysteries of this world. Though the adventure may be very tough, as many of the levels might be very difficult, but just believe in yourself and you can conquer them all!

I haven't thought of much of a complete story for it yet, but hopefully I can work it out in the end! And I hope you enjoy this Mod!

Swinging Light

This is a level from my new, upcoming chapter. It features a new cave-styled Goo which is featured in the second half of my chapter. One last thing is that the chapter could possibly have a level similar to my first addin, "Into Darkness". The level would use different Goo, and go by a different name, however.


My first level
OCD:40 balls
v0.2 add green text


My fourth level now is remaked!More challenge than removed version!
The first two are removed version screenshots!
The last two are remaked version screenshots!

Beauty in chains

When a Beauty can't go to a gear, you have to get the gear to the Beauty!

OCD is 25 balls (try to find out yourself where the extra balls can be hidden!) but it is almost the same effort to collect all 38 available.

The BLACK World
The level

This level has finally been updated!!

I finally decided to update the level. It's much better and a little more challenging than the last version. The level is much larger and I've added some deadly geometry to mix things up a bit.

I hope you enjoy the newer and better version!
