One of the worst best games I've ever played. This games world, characters, music are all incredible and so unique. Then the gameplay comes in and, while not terrible by itself, is ruined with its game design decisions such as waiting around for certain kisses to be available and repetitious backtracking. It's a very slow game all around. I don't even mind that a guide is basically required to play the game. But even with it, the game is still tedious. I reccomend trying it out if you really love it and sticking to a lets play to finish it. It really is such a great game besides all its huge flaws.

EDIT: I've recently watched this video about Chulip explaining how going into it with a more point and click detective mindset like say, Grim Fandango, provides a more enjoyable guideless experience overall. It'd better than expecting a random game about kissing like the game advertised. He goes more in-depth by explaining the card mechanic the game only briefly explains to you in an optional dialogue choice. These can show a lot of hints on what to do next and I think it's really surprising how the game doesn't emphasize this at all. I still don't think the pacing can be fixed with this and there might even be more backtracking trying to play the game this way. But I do think it might be interesting revisiting the game with this mindset. There are very heavy spoilers but I reccomend giving it a watch: https://youtu.be/Lrep_MVx9rk
