Question

so I hope I can ask this here, but I am thinking about getting Fate/hollow ataraxia REMASTERED on Steam while it's on sale, but I had a couple questions about it and the discussion tab is dead it would seem so I am on Reddit to ask. So when I was looking at the store page, I noticed a mini game type thing? are those mini games optional, and if they aren't, are they then easily completed? Also, when watching a youtube review, I noticed that the visual novel works are on the entire screen with like a shaded text bubble covering the entire art picture. Can that be changed? I like to read VN titles with a text bar/bubble on the bottom of the screen as I like to view the art without obstruction.
