Thank you for your kind comment.
Yes, I created it more as a concept than as a good game, and the installation itself already turns a lot of people. The lack of a tutorial is a bad decision I made because I didn't expect the game to be successfully launched by even a small number of people.
As for the blacklist, that's a good idea. I'll need to add it in one of the next updates, but it won't be soon.
At the moment, v1.1.2, I can only provide a solution with modifications. But it will require your time and effort. You will need a spreadsheet editor, such as Excel (I use LibreOffice Calc).
1. You can download all the tables and put them in the game's mods files %appdata%\Godot\app_userdata\Character Matrix\mods\characters\random or find the button for this in the settings menu.
2. You can modify any table as you see fit and add new ones, except for the all_races.csv table. It is the entry point. Unfortunately, all_races.csv is not read by the game, which is a bug, so any changes to it will not be applied. When opening and saving tables, make sure you set tab separator, not comma.
I have added the tables to the download list as [WIP] characters tables
