The two enclosed updater applications can be used to convert any version of "Out of this World" to version 1.0.3 of the game, which fixes a graphic bug on Power Macintosh computers as well as various other fixes.
To apply the update, just double-click the "Out of this World™ -> 1.0.3" application. You will be prompted to locate the "Out of this World" application, and then you'll be prompted for a place to put version 1.0.3. You should probably put version 1.0.3 in the same place as your old copy.
At this point the updater application will create a new copy of "Out of this World", version 1.0.3. Try playing the game. If it works, delete your old copy and use version 1.0.3.
If you encounter an error during the update, try again using the other updater application, called "Out of this World™ "mv" ->1.0.3". This updater will work on versions of Out of this World numbered 1.0.1mv or 1.0.2mv. You can determine this version number by clicking on your old "Out of this World" application in the Finder, and choosing "Get Info" from the "File" menu.
