This was a really nice visual novel! Loved how despite its fantastical nature, it still teaches the player about the need for self-education and consent, both in medical practices and otherwise. I feel like this is exactly what an edutainment game about blood donation clinics would be like in a world where vampires exist. And that's really cool!
Also Gakuto and Marie are awesome :)
Thank you very much for making this game, and all the best in your future game development!
