Inside, in a nutshell, is an INK-written game about exploring and finding the way out of the witch's mind which is filled with memories of the past all jumbled together creating all kinds of strange events similar to when a person is dreaming.
You can choose the name of the witch whose mind you are exploring and interact with her + the world around you in some ways which will decide what ending you get. I got the good ending on my first try (hooray for me) and decided the hide route with the husband. It was a nice and subtle berating sentence at the end about the loss of a talent, a savior and benefactor caused by the superstitious beliefs the people held. Another instance (Spoiler - click to show)is the memory of the witch's mother about to sacrifice her in the altar showing just how far can a person holding those beliefs go (remember the witch trials in medieval Europe).
As far as pacing goes, it was fairly balanced, neither too slow nor too fast. It doesn't tire me out playing through it which makes the game very enjoyable.
Surely, like another reviewer pointed out, I would like to see more descriptiveness when it comes to the scenery around the main character along with more passages to be added for the actions we take when entering the yellow framed window.
It's a game which provides minimal to average interactivity with the story and some sort of replayability but promises a good playthrough experience.
