Superb job! You have something truly remarkable here. The quality of the voice acting and the artwork is impressive, Akari is so cute. I enjoy NTR games a lot, but what really captured my attention was the thriller aspect of the VN. At first glance, this clearly feels like more than just another nukige.
Regarding the story, I’m curious if the tape at the beginning was real and how much the choices will affect the outcomes and routes. I’ve already tried all the choices in the newest version and noticed some promising branching potential, such as Rei not watching the tape and Akari being able to fight (and win) in the latest chapter.
Additionally, I’m curious if you plan to give sprites to all the characters, as the shadow sprites can be a bit distracting. I'd also like to know if the CG you posted of Akari holding a taser is in the game? i didn't find it.
Either way, I’m looking forward to your project's development. Good luck!
