Because the game is actually called Hypnosis? Because here was no crazy breast growth in first few updates/ year of development? Because DEV multiple times stated that Breast Expansion is just side ending and we will have main ending when side endings will end? Because game basically branch off at one point and we still wait for other part of story? It was like 2-3 years ago but still it is how that was explained by DEV.
Have he changed plans and have every right to? Yes. Can we expect he will tell this clearly to his former patrons instead of slowly abandoning this game and starting another? Yes. Will he do it? Time will tell.
You are completely wrong. Have you actually played the game? Game start with no girl in Love in him. Some were not even interested. All changed thanks to hypnosis. All the crazy sex he gets, girls addiction to his cum expecialy - thanks to hypnosis. BE - all thanks to hypnosis. Girls participating in harem, not minding family also banged, changes to girls decisions - all thanks to hypnosis. So no, this game up to lets say half of it would be practically identical without BE but would not exist without hypnosis.
What a nonsense.
"The game is called like that"...Yeah, seriously? THIS is even a point?
There was Breast Expansion right at the start. The first Hypnosis being done is a wish for bigger boobs. There is Breast Expansion in every pathof this game, including the Main Ending. The Boobs dont suddenly shrink before the Main Ending and none of the LIs is asking for smaller Boobs, they are asking for a stop to the growth, which still keeps the initial expansion.
Yes, one of the Side-Endings was about a lot of expansion, a scenario where the watch is gone. But thats about it, the whole game focusses on Breast Expansion and the Hypnosis is the way to go for it.
Also, just look at the Devs social media... Do you see all those posts involving mind control and Hypnosis? There is barely any breast expansion anywhere... /s
