There's a story here, but I'm not sure if I can really pin down what it is, or if I'm even qualified to. Yume Nikki is absolutely captivating from beginning to end, the exploration alone will keep anyone who loves that kind of thing going for a good while too. The sprite work is also incredibly memorable, with a style I've only ever seen afterwards in fan games for this game, funny enough. An absolutely relaxing, creepy, surreal, nostalgic, etc. etc. experience, that is definitely worth playing at least once.
