itch.io

by clicking on the value, you wish to change and the number you want as the amount, then click download as before clicking save as and finally on the save that you dragged into the box. once saved, reload the save  and the changes should be there

if you really want to skip all the grinding all you need to do is look up %LocalAppData%\HallsOfPaleWidow\Saved\SaveGames in my PC, then drag and drop the save file on the site https://www.saveeditonline.com then edit your money before saving the file in same spot. I recommend moving the original save in case you mess up. Don't want to corrupt your progress if you mess up somehow.
