Seems most people didn't particularly enjoy the mini games, some expressing their views more politely than others. Well it's less work for me if those scenes didn't exist. Those aren't exactly easy to code, so I guess I'm not putting in much of those from now on...
New to this thread and just reading through the recent posts since the update and figured I'd chime in on the mini-game discussion.
Personally, I never play these games without a walkthrough. I prefer to have the best-possible experience on my play-through, since I rarely re-play these types of games once I finish them (unless they get updates, of course. But once I finish a completed game, I'll most likely never touch it again).
That being said, I haven't seen the mini-game in chapter 10 yet, since I just finished chapter 9 and the Steph BDSM mini-game scene using the walkthrough posted in the OP.
I think the mini-games themselves are fine and fit the story. Steph's BDSM mini-game for example felt... natural? It didn't feel out of place and the choices/dialogue/outcome felt like it fit well. But again, that's from a perspective of someone who had a walkthrough to tell them what to do. And from what I've read in this thread, the chapter 10 BDSM MG is pretty hot, so I can't wait to see that.
However, I can see how it would be annoying to people who play without knowing how to win these MGs. Losing to the mini-game will just make most people feel like they have to reload the game and try again, since they don't want to miss out on content. Maybe some visual indicators for the variables would help? For example, the pdf walkthrough shows variables for "time required" for each action, and "resistance lost" for each action. If the mini-game UI showed Steph's current resistance, and showed what each tool did in terms of time taken/resistance broken, it should be a lot easier for players to figure out by quick trial & error how to win (assuming the MG had enough leeway for some mistakes and still get a win).
Anywho, that's just my 2 cents. As a religious walkthrough-user, I'm enjoying how these mini-games add to the feeling of the game and I think it makes this game more unique then most VNs that are just "click left mouse button until next sex scene", but I think there should be an easier way for people to know how to win while they're playing (without resorting to a walkthrough (like me, tee-hee))
EDIT: also, on the topic of walkthroughs... uhh... anyone feel like making one for chapter 10? The pdf stops at 9... Or point me to the game file I need to open up the see the variables myself
