VVVVVV

Old Version
VVVVVV is a flash game wrapped inside an .exe application. It uses a hidden flash cache folder in your application data.

Windows

 * shell:appdata\Macromedia\Flash Player\#SharedObjects\[random string]\localhost\program files\steam\steamapps\common\vvvvvv\vvvvvv.exe

Mac OS X:

 * /Users/[name]/Library/Preferences/Macromedia/Flash Player/#SharedObjects/[random string]/localhost/[location of VVVVVV.app]

GNU/Linux:

 * ~/.vvvvvv

Current Version

 * VVVVVV 2.0 is a C++ game. If you have the steam edition, you will have this version. Since it's not a flash game anymore the save games have been moved to a different location:

Windows
Mac /Users/ /Documents/VVVVVV/Saves OSX 10.11.6, VVVVVV 2.2: /Users/ /Library/Application Support/VVVVVV/saves
 * Windows 7: C:\Users\[USER]\Documents\VVVVVV\Saves\
 * shell:personal\VVVVVV\Saves
