Yeah no worries man. I'm just glad you could read all that. I hadn't realised that this game was made before CC, so some of those things didn't make a whole lot of sense, as like I said, CC was better when it came to some of the things I complained about here. There's still some things that link the two games in terms of my complaints though. Mind you, these are the only two games of yours that I've played, so I could be arrogant and you can disregard what I'm about to say:
The purpose is lacking, or often doesn't make sense. Sometimes something cheesy as "the girls being infected with a horny virus" or "you're the last man alive" is a whole lot better than trying to conjure up something that makes less sense. This is because something cliched is easier to overlook in a game where the plot only serves as an excuse to have sex with fictional characters. There's no need to figure out a grand plan, just a beginning and an end suffices. For my examples, the virus could end when all of the girls have been fucked senseless, and the gameplay serves as a way of convincing them, just like in CC. Just this time, there's a better reason for them to do it as it's believable. For the apocalypse scenario, the game would end when enough of the girls would be impregnated as to revive humanity. The point is, it's extremely easy to figure out a plot that makes sense, and the bare minimum is required for a game that doesn't need it.
As for gameplay, I'm all for casual, especially when there's visuals as good as these. I'm just not a big fan of repetitive grind that doesn't show much reward. In CC it was manageable thanks to the way some of the awareness stat was doled out to the Charas, but there doesn't seem to be any way to make it less grindy beyond that. I don't know what kind of engine you're using, as that poses its own restrictions as well, but something like minigames aren't a bad idea. Not that I need minigames for a game to be good, but it's something to consider when spicing up the gameplay.
Anyway, thanks for taking the time to read what I had to say, and thanks for clarifying some things in your reply as well.
