Found the save file, I was able to reset my progress and start over by deleting the registry key found at Computer\HKEY_CURRENT_USER\SOFTWARE\HotPink and Annue
To open the registry, press Windows key + r, then type regedit
You will see a directory bar at the top. Just copy and paste "Computer\HKEY_CURRENT_USER\SOFTWARE\HotPink and Annue" without the quote and you should be good to go (note: You may have to replace "HKEY_CURRENT_USER" with something else if you don't find it there. I am guessing most people will find it there). You can follow similar steps for any unity game
After that, on the left side bar right click "HotPink and Annue" and click Delete.
It will be different on Mac, I can't help you there
Disclaimer: This should be safe, but I advise against using the registry editor for other reasons since it could damage your machine. If you do any registry changes, you better know what you are doing (and no, deleting unused registry keys is not going to free you space or make your pc faster. It's pointless. Trust me I have a 10 year old rotten potato laptop that struggles to run Windows 10, and a Windows tablet that I was basically scammed out of buying).
This should also be very useful if you are experiencing any bugs or issues. It may fix it.
