Editing the gameIn the Properties directory in the World of Goo install directory there's a text file called "config" where you can edit some things. At the top of the file the programmers have left a humorous warning saying: "IMPORTANT WARNING: If you edit this file, your computer will probably explode. Your friend, the High Resolution Sign Painter"
Meat BoyFor the iPad version a challenge was launched to find the hidden Meat Boy character (from Super Meat Boy) in one of the levels. The first to report the correct location received a download code for the iPad version.
Savegame bugThe initial pre-order version contained a bug where clicking "Reset" could delete all the savegames. This was soon fixed with a new download of the entire game.
Steam versionsPeople who downloaded the pre-order version could use their activation keys to register the game in Valve's distribution application Steam and download it again there. That way, those who got the game early could also have the achievements that were introduced with the Steamworks integration. The initial Steam release was only available for two days for European customers (13th and 14th October 2008). Because the retail European version would only be released in February 2009, the publisher demanded it to be pulled from Steam. Customers who bought it during the initial two days could continue to use it and worldwide downloads were still available from the developers' website 2dboy.com.
US retail Macintosh versionAt some retailers, boxed Windows/Macintosh hybrid versions of World of Goo were sold that accidentally contained a Windows installer only. This included boxes sold by the Apple Store, Best Buy US, some German game shops, and possibly others. However, the Macintosh users were not left out in the rain as the developers offered a free Mac download to those affected, besides the usual publisher replacement option, that is.
