I want to say I love this game. The plot is great, the writing is fitting, the characters are all extremely likable, and the MC has a lot of personality for an otome game. I'm sure it will be great once it's complete.
That said, Act I is just an introduction to the world and (some, not all) ROs. The story is just barely getting started by the end of Act I. When it ended it left me feeling frustrated, for a number of reasons. (THAT ending, aargh.)
If the other Acts hold up as well, this could easily become the best otome game ever for people like me who like their dating sims on the angsty side.
I definitely want to see how Elfriede's story continues.
