I don't know what is the purpose of the dreams where Hana shows the MC how a robot takes over his old life and seems to be better than him in every way possible. Those dreams just piss me off, so whenever one starts I just use CTRL to skip it. And I wasn't really that thrilled with the conversations with Hana, but ever since she turned the MC into a plastic duck, I've decided it's best to skip them too and avoid the question round by choosing not to ask any. At this point my only goal with Hana's dreams is to end them in the less posible time and not see anything that happens in them.
Also, I truly believe that the two goddesses are created with the sole purpose of making us hate them.
But the rest, the part of the game where Hana doesn't exist and the goddesses' participation is minimal, is pretty good. The game would be much better if Hana had never appeared and the goddesses were a bit more pleasant to deal with.
