I have located a possible rip off to Demon Girl - it is different in some ways, but story, setting and some of the cinematics are quite similar to the point of cheap knockoff - see for yourself:
Someone's got a bad case of Quadruple Denial, but it's easily curable. Just admit that you want your father (substituted psychologically by the surrogate Linemarvel) to show you more physical affection, like hugs.
Derper. It's a LineMarvel Tribute, which you would know if you lurked a bit more and found the the Angel Girl thread in the LineMarvel section, and the Angel Girl X thread in the Hentai Games section.
1: I've seen both of those threads because I do pay attention to this forum.
2: I don't care if it's a tribute, homage, or whatever you want to call it, I was simply noting the similarity.
Maybe if you weren't so dense, you'd see the difference between an accusation and an observation.
