Well, I just tried out version 1.3 and the problem with the white rectangles is much worse. What's going on? (OSX iBook G4)
You need to merge the files from 1.2 with 1.3. You probably haven't copied the files from animation.
1.3 waits forever on "complete" at the end of the level. I can continue with escape, but should it happen?
When you install the patch on OSX you have to copy the files from the animation folder in the .dmg to the animation folder in your gish folder. If you copy the whole animation folder it will over write the existing folder and erase all the files. Not sure about the ending for level 1.3 let me check.
VERSION 1.3
Edit: Wait... It was because I duplicated the old version and then copied the new files to it (just in case...), but I accidently didn't put the sound folder in.
Ok so its working now? Like I said if you use the OSX patch you just have to copy all the animation files into the current animation folder, everything else can overwrite. If you know a better way to do a patch for OSX please let me know.
A better way that just came up in my mind would be an Applescript. They're very easy to write. You can ask the user via the GUI in an "open" dialog for the Gish copy to update, do a basic "is this a copy of Gish" check and then use the shell (which is accessible from AS) for copying the files. Applescripts are not very fast, but certainly fast enough to do this. I'll try to write one...
Edit: in ASs you use pre-OS X-style paths... so we need conversion, recursing via the AS (not recommended for many files - slow), or another way.
