The problem isn't sandbox. Most of the biggest and best harem porn games are sandbox ( harem hotel, the headmaster, dark magic, treasure of nadia, corruption, sisterly lust, lessons in love...etc). There are some amazing linear games but since linear content can be quickly consumed and you have to wait months for new content, it's dissapointing for a lot of people. Like for example even no updates for months, you can return harem hotel and fap to it time to time since there are hundreds of repeatable sex scenes in the game. The problem with this game is that there is very little repeatable sex scenes. You can't have a sandbox games with so tiny amount of repeatable sex scenes. There is no point to play this game after you unlock the scenes since there is nearly zero repeatable sex content. That's it. Nearly all the sex scenes in this game are non-repeatable scenes. Which is kinda bullshit if you ask me. Still I love the game despite that. I hope we will get more repeatable scenes in the future. Because as it's, I cannot even consider this game as sandbox because how little repetable sex content are
