Great game! the artstyle is a perfect mimic of the original source that is even used as a base story in this parody;
The mechanics are well thought and designed enough to have a deep and progressive interaction between the PC and the NPCs;
The content is reasonable, and it always keep it updated,the H-scenes interactions are very intuitive, graphically speaking, there isn't too much content on this matter, but still satisfatory;
A better look on the interactions clearly shows that its the main factor on this game, its core, since the variations are wide and there's already set up an immense blanket space to it fill on even more later;
Sadly the developer, Oni; don't want to much involvement of other programmers, even those that applied for free to help him out that are part of his fanbase, took years to him accept outside help, and in his case is essential, since he practically learning from scratch how to deal with the game while making it by himself, now even with a few others helping he still still producing too slow & low content, its been years of development and it barely changed since it first year, its almost on the Togashi-level of productivity;
Anyway, the game is still an Amazing DEMO, and I hope that my grandsons will be able to enjoy it properly when its get full released. =)
