Wow!! Thank you so much for the incredible feedback! I loved hearing all of your thoughts. I'm glad that you enjoyed the visual style! I experimented with a few different ideas to make the visuals look unique since I know that my art skills are not quite up to the incredible level that some other VNs have.

Haha, I agree that Sei and Shizu's relationship is frustrating! Shizu is a relatively level-headed person, but she's only a blockhead when it comes to her childhood friend, and Sei is a comically poor communicator. Their mutual insecurities play a very big role in their dynamic. I also played relatively heavily into typical cliches in the beginning for the rug pull near the end. (I only hope other players get that far!)
I won't spoil things for you, but you had some good insights! The plot and the relationships between the characters evolve in some interesting ways later on, with plenty of drama. I hope you enjoy it!
Again, thank you for playing the demo and for giving me your feedback! :)
