To be honest, the problem usually lies in the fact that the older version officially published here has the most stable code and a complete localization version for the languages listed on this site in the description of the game.
And in the version that is published on third-party sites, there are usually many starting errors and there is no localization for new scenes.
Therefore, using an unofficial copy, the player experiences problems with localization and stability of the game.
On some sites, so-called mods can be added to the game. Their functionality depends entirely on the honesty of their authors, but they may well ruin the save of the game.
Therefore, if it is possible to support the author with a minimum amount on Patreon, it is better to do this and have access to the latest version of the game.
If money is tight, then it’s better to wait and get the stable version of the game here.
