Its an important part of the story, maybe thats the point to have that scene there, haha! You can Use the bat so you wont have to see this scene
I always use the BAT, and if you play more you will have a satisfaction using this bat again and again!
I did play more, still don't think it's needed from a plot perspective. Heather could instead have a few "inner thoughts" around the MC revealing she enjoys being watched.
(How i would have written the story element: Heathers son gets off watching his mom and his mom gets off getting watched by her son/son+MC. MC to the rescue helping out both mother and son. What a selfless and helpful guy hah)
Again this is just one random dudes opinion/thoughts, take it as you will.
As for the videos in-game, it'd be nice with a way to skip forward in them, though it might be a feature i've missed that is already available.
Either way, quality renders/animations and seems like thought and care was put into the game.
Can easily recommend the game, though for greedy bastards like me, there are story aspects/elements i would have preffered different. We can't all be in the same boat, but we can at least share the ocean.
