Haha, I'm glad you say I understood the game so well! Makes me happy!
Even though I wanted to wait before replaying, since I've finished another game in the meantime to clear my mind, I guess I'll be able to try Arantis's route sooner than expected, actually! Though, as I said, I'll go deeper into the routes once I'll finish them all (well, all the good endings at least). But I'll probably comment anyway once I'll be done with him.
On a side note, is it possible for people to die in the game? I'm pretty sure Lysadra or Xander can die at the end depending on how friendly their relationship is - in my case Lysandra wanted to do it, but Xander decided to intervene, and in the end both survived (wich I guess is the key for his good ending, by the way). But I have a feeling Osario and Arantis could die too, am I right? Since I knew Osario liked Lysandra a lot, while Arantis a bit less, I've left Arantis to deal with Adrien, and took Osario with the team for the final battle, then refused to follow Xander's plan during the climax. I simply don't have the heart to try and do something else since it may mean someone's death, but I still want to know haha
