I do hope you make it a classical vn. Sandbox is really a pain to play.
I haven't played it yet but I also hope that that cheating bit*h gets what she deserves.
I have ideas of it going to a classic VN at the end, but because of the fact that then taking it to sandbox/ free roam will be a lot of wear and tear and very difficult because of the impact of the last decisions.
Chapter 1 has the "sandbox" more "hard" even so there is no grinding and those things, but it is to know the places and the "realism" that the girls have their daily routine for which, you have to go to the surveillance cameras to see where they are.
So, if you are a Classic VN lover and you are bored with the lore outside the H Scenes, this VN is definitely not for you!
For example, the sandbox/free roam is for exploring to chat with each of the girls, see how they act depending on the items, see the locations, etc.
Chapter 2 (where this update starts) is a more "adventure game" style, that is to say, there are less interactions, or they are more controlled.
Maybe making it more dynamic.
Now in V0.6 (the one I'm working on) I'm doing something like this, but more complex, more interactions and secrets to discover.
I have to "thank" in part to the latinos, since they give me their support (and the, literally, 3 people I have in patreon) and motivate me to at least finish the VN.
Norman Knight, you kindly offered to correct the translation, the people who at least morally support me like the "Sandbox" or "Graphic Adventure" elements is what distinguishes it from most of VN (my style and the use of them in the narrative).
I'm an independent Dev, a guy who is just taking his first steps, it's also important for me to make something that is fun to play for myself, because if it's for profit and hate... I should have already closed this since version 0.1.
