I think nearly all of you will still have the problem to save correctly. As
Ladydarkness stated, you have to create in your game folder a "Save" Folder and in this Folder "Slot1" to 3.
After trying some stuff with the .txt, I can assure you the game works perfectly fine with loading the stuff. But it doesn't save the files correctly. (Edit: The problem seems to be, that the game doesn't "kill" the old .txt files or isn't able to overwrite them. A very simple own written program would only kill all the files, so that the game can make a new save file)
It's still not a perfect solution, but you have to simply delete the old save files and after that, you save your game. If you just want to play the game without grinding, here is my save. It has a lot of money, some stat upgrades, every cloth unlocked and no quest done at all. If you need a save with only the money or anything else, write me a message. (Edit 2: my save file is from Game Version v1.10.1)
Edit 3: ok it still doesn't work, you have to use the solution from
droxu. For some reason now, it won't load the stuff when you change between levels ._.
