I just want to say that your passion does not go unnoticed. The focus on real gameplay is something that rarely draws attention and support. I'd say that the vast majority of players treat any gameplay as a means to get to the H. Part of the reason is that most porn games have garbage gameplay, but I think they just don't have the right mindset to enjoy a gameplay driven eroge. Most people have come around to appreciating "story focused" adult games these days, so maybe people's concept of gameplay focused games will change too. Many people around here got so fed up with bullshit sandboxes, walking around simulators, and stock RPGM battle systems that they just don't want to be bothered by time wasters. Even the idea that the gameplay actually could be fun in itself is probably foreign to some people.
Anyways, I wish you success and fortune.
