@loop I won't say its a typical isekai game you are talking about, the tower is something more than that.
We don't know the purpose of the tower and the tower still has a lot of depth I don't think the tower is as simple as a game world like other Korean manhwa.
And the art work are mostly done by siu assistants so they are bound to be consistent and non consistent and isn't this flashback a story about traumerei sins or what are you talking about
