Tooltips are when you leave the cursor hover over the button and you get a little bubble or explanation of what the next scene will entail.
But just a little tip, if and when you edit Willow, have a scene where she and Steele discuss her fetishes and her fantasies. Even if this is just a game, Willow's BDSM tastes go from 0 - 100 in no time flat. Slow things down, have Willow take the time to talk to Steele about what she likes and if they are okay with that.
