I decided to post my PoG addins outside the main Platforms of Goo page.
To install this addin extract the zip file into levels folder of your Platforms of Goo (inter folder and GoosweekSpecial.ord.txt file should appear).
Goosweek's Special Level Set
is a set of PoG levels dedicated to really good players since most of Specials are much harder than any level in official chapters. Because of the difficulty, all of those levels can be skipped, and there's no need for solving them in order.
Some of Sepcials are showing features and inventions to inspire level designers.
VERSION 0.2 IS OUT!!
