Demo 2.0 was amazing! I liked the updated graphics and interface. The choice in the end of the battle looked especially impressive. The battle scene itself was great, I liked every single detail of it. My favourite part was when the petals fell.
The new CGs are so well drawn. The artwork depicting a certain scene in the flower shop scene is so pretty *__*
I found it intriguing that the opening sequence (which is very stylish, by the way!) mostly features the Sakuma siblings. Makes me think that Kotori had forgotten something really really important. (Lets hope he won't end up becoming Sarina's food in one of bad endings...)
Let's move to the story itself. I enjoyed Itsuru's character arc so much. She's an interesting side character with her own goals and backstory. I also liked her teamwork with Kotori. Itsuru's story has been told so I doubt she will have a role in the later plot, still it felt nice seeing Kotori interacting with someone who was a new acquaintance rather than a forgotten person from his past. That's why the Normal End seemed to be a logical addition to the TRT scenario before it branches into routes - Kotori did deserve a peaceful break after all those things that happened to him.
