As for me, how the creator ended this game is not that tragic. I know no story has an ending (except maybe Amy's story, which if you took her seriously, had a pretty good ending. Something like They lived happily ever after ). I even liked the concept (possibly not intended, but only caused by an accelerated ending) that the game actually consists of 9 games, stories that, although related to each other, are not mutually exclusive. Of course, some of them ended too quickly and without any conclusion whatsoever, but the fact that I didn't have to choose between Amy's really touching story and Sophie's hot and deep love feels like a good idea.
Let's be honest with this question: How would the MC resolve being in relationships with all these different women? It cannot end well. Either you have to choose one, or the harem ending, but unfortunately the latter, in most cases, the creators are not able to present deeply enough compared to the first variant.
My biggest complaint is that the Mayan story is so brief. The idea and possible development could be as deep and touching as Amy's story. What can I say, most of the stories need a little more to be called finished. I hope that the Creator can make a continuation and it will be divided into separate stories in one world as well.
