Obviously, the sandbox here is having a map to navigate around and that's it..... I don't think the mere presence of a map makes a game a sandbox.... It's not exactly a sandbox, I'm afraid it can't even be called a game.... A game should have gameplay, and if all you do in a "game" is choose who to watch pictures or animations with...
I don't like this game, neither externally nor internally...
A lot of game makers are trying to make their VN look like a game... By adding "sandbox elements"... As a result, it turns out that to watch the usual VN you have to click on the map to continue watching VN.... And it's infuriating... I hate VN and turn off this prefix in the advanced search when looking for a game.... And here I am looking for a game, not VN, sandbox, anal, ntr, good rating, etc... You start to "play" and it turns out that it is VN, not a sandbox, no ntr and in general there is no use of tags, because you do nothing in the game, just look.... And also that to advance in the story needs a certain number of times to perform the same actions ... Yeah.
