Hi. Had some issues getting the game to run in Linux, Ubuntu 21.10 but found a workaround.
Crashed on startup with this in the log file:
2022-02-02 22:46:52
Input string was not in a correct format.
System.FormatException: Input string was not in a correct format.

The issue seems to be related to locales/languages and using commas or dots as decimal separators. I'm on LANG=sv_SE.UTF-8 which uses , as a decimal separator, i'm guessing the game assumes . as a separator.
I solved the issue by running the game with a different locale that uses . as separator:
LANG=C ./Melkhior
After starting the game with the correct locale i got this in the log, i'm guessing the game wrote some commas in the config file while on the "wrong" locale:
"Configuration file could not be read correctly. Default settings have been restored. Please click OK then try launching Melkhior's Mansion again."
Maybe you need to set a locale for XNA / FNA / Monogame to use as default to have it always getting the correct decimal?
Hope this was somewhat helpful, seems like a really cool game!
