No, you´d just need to find the file(s) via the cache/temporary files, most probably somewhere in %APPDATA%. I'm not sure where files are saved for Incognito mode though, but it does save cookies temporarily, since it saves your login for the duration of each session. Maybe Google knows...

Ah, no incognito for games, got it! Depending on the game, you probably COULD extract the temporary game save from your current browser session, and keep playing it outside incognito, if you know your file locations and stuff...
