My god...
listen, the game's gallery or save or password or code is generated randomly, everyone's game uses a different code. when the game is started, to make it work, re-extract the zip archive of the game, edit ./www/js/plugins/YG_Extension.js and change it to:
84 checkGalleryCode: function (code) {
85 return true;
86 }
this will work for all versions of the game.
Next, start a new game, go to the left to your tent, go to the guy with the hoodie outside, enter anything in the field, voala gallery unlocked.
I seriously can't believe that the russian devs tried so hard to do encryption when the source code is plainly visible and anyone can edit it before starting the game.
