I thought of it as a pretty mediocre VN at first but it has some sweet details in the love routes despite the cliché characters and story and the mediocre art. I wouldn't recommend it but it wasn't an unpleasant reading either.
I loved the melancholic atmosphere it creates. Leaves lots of questions unanswered, but it's not something necessarily bad. I would have been fine with a more depressing ending too tbh.
The good ending is unnecessary long and you may end up with a lot of plot holes if you decide to go for non-romance route first, but it's good overall for a free game.
