Windows users: if your save file is gone... i tried this and worked:
First, make sure that your windows explorer is set to show hidden files. For the first location, go to your main drive on windows explorer. Then, go to “users”. From here, go to the folder with your computer account name. Then, go to the “AppData” / “roaming” / “Macromedia” / Flash Player / Shared Objects / one folder with seemingly random letters and numbers. “chat.kongregate.com”. When you’re here, copy its content (Click the first and last item while holding the shift button to select all). Now go back a few steps by clicking the “back” button until you reach the “AppData” folder and click the “local” / Google / “Chrome” / “user data” / “default” / “Pepper data” / “Shockwave Flash” / “WritableRoot” / “#SharedObjects”. In this folder, you should find a folder with seemingly random letters and numbers. Enter it / “chat.kongregate.com” and paste the content of the first location here.
