I'm curious what the point of the sandbox is in this VN. Right now the only thing it's there for is to give the player the illusion of choice in where to go. Since right now you can't use it to go anywhere other than where you're meant to during the story. Every where else is "you can't do that right now" essentially.
So far the story has been pretty linear, it's not like with Goddess' Whim (?) i think it's called. Where you can advance different storylines at different paces until certain ones are hardlocked until you progress certain stories.
There's the menu for training with the goddess, or some menu about powers... but again they aren't used still. So I dunno. Feel like it would be better as a standard VN with some choices sprinkled regarding content/kinks you wanna see. Unless of course we just haven't gotten to that stuff yet in the sandbox and there's going to be some kind of Guild quest thing too to go along with the powers.
Oh, almost forgot about the end of an update freeroam to get some scenes with the girls, but that also seems jarring in its own right and I dunno how that'll be implemented at a more full release state. Unless... that's all the sandbox is really for. Just end of update sidequest freeroam
