My friends, as of v0.1.8, Project "Mnemosyne" takes very seriously into account the decisions made throughout the game's development. These decisions lead to certain routes being considered in favor of others and guide the game toward different endings. This Mod attempts to keep all routes open and allow the player to see all the scenes. Since the game's original language is Russian, significant changes to the script cannot be made without losing the English translation.
To show all the scenes and set up all the variables for the different endings, this mod stopped asking certain questions that were part of the original script. Instead, it shows the scenes that would have occurred if both options could be chosen (since MOD: Both. is not available). However, most scenes have confirmations that allow you to close different character paths.
This leads me to raise two very important issues: 1) The Mod was retrograded, so it's advisable, I would say essential, to start a new game. 2) If you don't agree with the Mod's handling of decisions, don't install it.
