I can tell that this game has an immense amount of work put into it.
However, so far it's only been reading, which is a personal preference—I'm not a fan of just reading a story, I like to take decisions.
If you're someone who likes visual novels just for reading, then this game seems to be for you! What I've played and what I've seen in the game files show that a lot of work has gone into it!
I saw that the game looked really good, so I felt the need to mention it, but personally, this game isn't for me. ^^
