The difficulty is based on the difference between how much favor Lisa has for Kord vs how much she has for Yuto. At up to date, if you haven't played the fingering minigame at an earlier point, with the favors being 115 for Yuto and 75/80 for Kord, that minigame is damn near impossible, I doubt I'll nerf it just because I think it makes sense for Yuto to not be able to make her cum with just fingering at that point in the game, instead I'm thinking about adding more acts that they can do in the future but Yuto is not a main focus right now so don't hold you breath (Though I also doubt it's that many updates away since it's a long time coming).
For now though, if you really want to win it, I recommend either doing it before the turning point or just going into the wrench -> cheats -> change fingering minigame difficulty to "Easy".

I was at 125 to 30 when I tried the finger game the first time (which took like 10 tries), and I got it to 126 to 30. After reading your response, I just had my second victory, and got it to 127 to 30. I am already on the 'easy' difficulty, so I guess I will just practice more.
I realized early on that the game was favoring Kord over Yuto, so I wanted to work on the underdog Yuto.
Thank you for creating this game and taking the time to respond.
