The save file has been verified on multiple accounts (Yes, the online game has offline saves; I discovered this myself when the game froze on level 3 and refused to start).

If saving doesn't work (even though it should), then download the engine cheat and the free purchase cheat and hack everything in the game as you want. Surprisingly, everything in the game can be hacked.

Installation instructions:

Download the file;
Drop the save file to this path: C:\Users\Username\AppData\LocalLow\GreenT\SlutSquad.
Enjoy.
