I'm not even sure what to say- everything about this is fantastic. I'm actually pleasantly surprised that you didn't put a definite price on this, because it's amazing. I'm also really glad you made a second one with a price- you deserve at least some income for this masterful work.  I've thoroughly enjoyed four story endings I've seen so far, and I'm so excited to get through them all! The introductory video is lovely, and I'm impressed that you wrote the lyrics. The characters are lively and wonderful, and tend to stray away from common tropes or stereotypes. Yes, there may be hints that Sam is a, "Tsundere" or Matthew is the "adorable otouto", but it's really well written, making the characters seem more three dimensional. The CGs are gorgeous and the story is heart-tugging, suspenseful and sweet- even the fourth time 'round. It kept me on my toes the whole time! As for the controls, it's very user-friendly, even allowing for players to know when they've said the right thing to a said character. The voice acting is easily one of my favourite things- it adds a whole new level of personality and intimacy to the characters, and overall is just very charming. I'm happy to say that I will be buying the second one later on today! Very well done!
