Sorry for the late reply. I have been working on the tool. I have added somethings in this save file. To answer the question when will I be done with the tool, I'm not sure. It could be a week or more. I keep hitting roadblocks. I am able to use...
The tool is still a WIP. Are you able to send me your save file. If you are able to I can add whatever you want. If not I can always give a starter world save with everything unlocked and all up to date store items.
Its definitely possible. Hex editing does work but I much prefer edit the game save file. I am able to get in item in the game. I havent tired to get moonstones yet but its unnecessary. I have got the choco croc even though I did not play back...
