Usually you take your downloaded update version of the game, open the main folder it, then highlight all the files and subdirectories in it and drag those into the old game directory. Then click to overwrite all files.
My mind was blown when mom went from totally reluctant to a 100% slut in like 3 slides. I dunno...seems out of the original's spirit.
Anyways, Dev says he's going to rewrite the first part of the game, so no new updates for a good long while.
For me, the slow burn with a lot of teasing is even hotter usually than the resulting sex scene. However, if there is never any payoff, that just sucks. That's the risk of in-progress games that may be abandoned at any moment.
I like a reasonable slow burn, and to me that is pretty much impossible for more than 3-4 love interests. I've played harem games with great models and animations, but lose interest when the MC just starts banging random chicks in bathrooms.
Have had several, MMF and MFF. And one foursome. Had a chance at a fivesome once, but didn't like the vibe of a couple of the other people involved.
All pretty damned good.
I love games where choices can put you on different paths. In such games, a walkthrough is often needed because of otherwise hidden modifiers and triggers that are needed to change to a different path. So, yes, very pro walkthrough.
There have been games in the past that I have played and did...
