These cheats are ONLY compatible with Princess and Conquest STABLE EARLY ACCESS version 0.19.12 (1 Dec 2022).
These Cheats WILL NOT FUNCTION on any other version. If the cheats aren't working for you, it's on you. I have confirmed they work.

I've seen some people ask how to use the cheats. So, allow me to help.

After the intro is complete, a new option will appear in the menu.
"Cheats"
If you select that menu option, it will give you a warning about not getting achievements anymore.
If you're ok with that, enable the cheats when asked.

Once enabled, a window will open with 6 0's on it.
