These cheats are ONLY compatible with Princess and Conquest STABLE EARLY ACCESS v 0.20.01 (26 Jan 2023).
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.
