Hey! It has a few sandbox elements, though I have not fully implemented them. It has a lot of VN-style scenes, but I also like to give freedom to the players to choose which girls they'd like to interact with! Therefore, girls will stay in different places around the college, and you can choose which one of them you would like to dive into their stories. But while you're in the prologue and the game presents the mechanics, you'll have to talk to all of them. But later on, as the updates start to progress, you'll be able to choose. :)
