This game single handedly showed me what an Adult Visual Novel could be. This is the cream of the crop. A MASTERPIECE if you ask me. If I could get an hour with any developer on this site to learn something from them, this would be the developer I chose.
That being said, does this game have an end point? I feel like I completed it a few years ago, but now, it seems to get to spot where you can't continue with anything new before you can even sleep with the cousin. It's hard to keep up with all the remakes of original games so I don't even know if this is the original.
