The Witness is a very difficult puzzle/exploration game set on a mysterious island.
Pro Thought provoking world
Even if some of the puzzles are rage-inducingly hard, the world of the Witness is really peaceful. It's an uninhabited island littered with stone statues and mismatched environments. Yet none of it feels out of place. It is really intriguing to explore each new area, especially because you can find voice recordings in them. At first these may seem like simple audio logs, but each one contains essential clues to gently shift your thought process. To succeed you need to shift your perspective and think outside the box.
Pro Vivid graphics make you want to explore
Everything about this game leads you toward exploration, even the graphics. They're very vibrant and feel alive, invoking in you a sense of wonder. This is thanks to a great variety of colors, ranging from wild, hot pinks to more subdued ocean tones.
The colors are also used contrast the environments and make them stand out. For example, there's a location painted orange autumn colors next to a grayish-white quarry.
Pro Cleverly designed puzzles
All of the puzzles use a simple concept where you draw a line from point A to point B to solve them. This could get old really fast, but the developer has thought of many ways to keep it fresh. While the regular variants are just maze puzzles, they gradually get new layers added to them. It can be symbols you have to separate, panels you have to look at from different angles or clues in the environment. Even after solving around 300 puzzles, the new puzzles you encounter will still feel exciting.
Con Some puzzles might be impossible for the colorblind and hearing impaired
Certain puzzles use colors to hint at the solution. If you're not able to tell them apart it may be impossible to solve the puzzles.
There are also that puzzles require you to listen to the sounds in the environment and use them for the solution. Some of them are masked with sound effects such as car horns or birds chirping, making the puzzles hard to solve. This becomes a lot more difficult if your hearing is impaired.
