I love world building in Lust Shards, and as a day 1 reader, I like the way that the writer expanding the world which make it much more enjoyable to invest in lore and reading every line of text to gather information or lore-drop.
And I'm glad the writer understood that getting reader to love the world and it's setting is key to hook the reader for fantasy genre.
In very early build the world is pretty much "This school teach student to kill horny monster. Go kill or fuck it idk." and minimal outside world exploration. However, in later route we get to see more of the world outside the academy, introduced to nightfallen conflict with 'City Animal', we get to see student's point of view to nightfallen(Some thinks they just a monster, some thinks they're a being that deserved respect.) with that is what make the world of Lust Shards so intersting.
Sure, Lust Shards have tons of flaws and by all means not a perfect vn, but certainly a captivating experience and deserve the praise.
