The game is heavily inspired by Virtual Succubus. I used to support Virtual Succubus, even donating quite a lot of money.
When I was disappointed by some changes to VS, the developer — who is quite famous for being nice — told me to go f**k myself and my own game xD.
I liked VS, but over time, the game got worse in many aspects. To this day, when I play VS, I prefer the versions prior to v.24 when it comes to endings.
You can also check that versions like 17 or even 14 had a better-balanced algorithm, more scenes, and more visual variety than the current version.
I want to create a game that is not only an improved version of it but also has its own identity.
