While I agree with some of your statements, I think it's essential to consider that the reason the story seems simple so far is because it's a demo. I'm sure that as more updates get released we'll see the story grow to be more dramatic and thrilling.
You mentioned that this story is intended for a female audience simply because the MC worked as a waiter and has sleepovers. What do those two things have anything to do with the MC's gender???
Also, what's the point of you playing IF games when you think the majority of them are mediocre? Making that sexist comment about men taking criticism better than women was also completely unnecessary. I think your original post was pretty solid in terms of criticism, but all your other replies afterward are just rude and lack any tact.
