Explain how it is NTR if the game treats both copies of the MC as the singular MC. There is no difference between how the game refers to either clone. The girls have sex only with the MC. Also, people keep using the word "cuckold" wrong. To cuckold the man has to be aroused but the humiliation watching his girl be with another guy. That doesn't happen here as he chooses to create his clones and there is no humiliation on the MCs part. The only NTR in this game has been the completely optional, non canon, and skippable if you don't want to see them, bonus scenes with Jessica. The game even warns you before activating it, so if you saw those scenes, you are the ones that ignored the warnings and watched them.
And to those saying "listen to the audience" you need to get out of your echo chambers. The people that are actually paying the dev on Patreon, and the people commenting on their discord (which you get access to by becoming a paid member) are enjoying the new update. The complaints are focused on the bugs (which for the initial release of an Inceton game has actually not been that bad for once), not the story content. You are basically asking the dev to listen to people that pirate the game vs the people who pay for the game.
