The story is wonderful and the gameplay is scary enough, making it really fun but some of the steps to get through the endings are really confusing or not enough clear to understand what to do, making it easy to miss the core steps that change the endings. In general I enjoyed all of the game, but if you don´t like to see guides or walkthroughs you may have to spend a lot of time on trial and error testing and searching things to solve the puzzles. (The "fanservice" is fair enough to entertain, but don´t expect too much, because most of it is a horror game)
