Uhm so sheer curiosity got the better of me with this, not much I would actually rule out when it comes to games so I thought I'd at least give it a try.
So, artwork.... these GILFs aren't the most beautiful creatures, but a weird part of me kinda digs it... Mainly the over-exaggerated bodily features really, stick a paper bag over their faces and I'd be good to go!
But in all seriousness, I do feel like some of these characters have been deliberately made to look ugly as well as being old. (but hey that's just my opinion).
Maybe the dev could maybe tweak the faces ever so slightly, still keeping that old GILF look but maybe just making them a little bit better looking.
Personally though I'd change the hair on Linda, as that current hair does nothing for her and I'd probably say she has the best body out of them.
I know this game is still early on in development, but that restart after every final is a tad annoying.
I do actually look forward to seeing where this game goes. Personally, id be sticking with the women who are old but not grey and I am looking forward to seeing Setsuko in action.
In terms of story, id like to see the MC progressing and revisiting these characters and having somewhat of a friendship level which increases and introduces you to more events. It would be interesting to see some other fetishes such as pregnancy (i know they are old, but it happens), maybe a bit of lactation, breast/ass expansion (I know, even more!) and probably squeeze in a few others in here.
So yeah, it's a weird game, definitely not to everyone's tastes, but it has something,... not with the faces though, but more with the bodies. Ill be keeping an eye on this one, and wish you the best of luck.
