Don’t judge a book by its cover. It’s an easy concept to come up with, but not nearly as easy to put into practice. Undertale does this with its monsters actually being friendly rather than things to kill; Ib does it by making the most beautiful flower turn murderous.
Ib is a free RPG Maker game that takes place in an art gallery. Within moments of playing, you’ll find yourself in a living gallery where no matter where you go you’re under attack and need to flee for your life.
Things with seemingly mundane natures, like a woman in a painting, jump from the wall to attack you. Ib has several moments where something that should be considered spooky for the 9-year-old protagonist, isn't actually dangerous, or even if it is it's not malicious. In Ib, we are shown that while many flowers have their thorns, not every plant is dangerous in this gallery.
