World of Goo is pleasing to look at. Most of the time it's very colorful and joyful, but it changes from time to time to reflect different parts of the world. Nevertheless, it is stylistically well presented throughout the game.
As you start playing there doesn't seem to be much of a story. A few philosophical messages left behind by the Sign Painter and a cut-scene here or there. But as you progress through the game you unearth different details about a slightly disturbing world.
FEZ goes beyond just being a great puzzle platformer. It also has a very clever storyline and game world with a mysterious bygone civilization that fits perfectly with the mysterious puzzles of the game.
There are many secret mechanics to be discovered in the game. It may take a couple of playthroughs to discover them all, but when found it will make for a mind bending discovery. How the game appears is not how the game is actually being played.
Lots and lots of puzzles, and multiple ways to finish the game. Comprised of mainly block moving puzzles to progress room to room in the games dungeons. While there are a few other puzzles throughout the game, mainly block moving is what the player will be doing.
