[...]It is a clone/copy of the original game, it's not like aleksey has made any major changes that is different from the orig game[...]
Yep, just minor changes like the removal of Olivia's boyfriend, Kate and her mom, the introduction of Kira's coworker, the extension of the known quests, lots and lots more renders and variations for each event, the new quests like Lisa's movie night, Alice's revenge, continuation of the couch event and so on.
Major changes are hopefullly still to come, some starting with the one in the next update, where Max and Alice actually leave the house together (most likely to get that Black Cat outfit for her show).
At least there are some minor details that make the games distinguishable.
Btw, The clone of the original game (with Eric/NTR extension) is to be found on the BB Remake page.
