I think I found a way to cheat without cheat engine which I didn't see in the thread from a brief search
1. Create a save file which creates the files xxxxx_extend.qt, xxxxx_extend_binary.qt and resolution.txt in the folder h_storage (with xxxxx replaced by some number). Then close the game
2. Edit the values xxxxx_extend.qt with notepad. This requires some experimenting to know what corresponds to what. Some obvious fields to edit are level (your job title which goes from 1-11), exp, attrbuteList (which contains money, strength, health, libido) and addPhysicalLimit (which increases your max strength).
3. Delete xxxxx_extend_binary.qt
4. Open the game, reload your save file and save
Attached is a new save I created with hacked money, strength, health, and job - for those who are like me and want to play the game through but minimize grinding. Seems to work ok so far, just don't increase your health or it will reset back to 100 lol
