Braid

9.3/10

Braid is a puzzle-platformer with many different mechanics related to time travel. It's brilliant, original, clever and still very artistic. It showed many what indy games could be and more than 10 years later it's still a solid recommendation. Even if these days the indy games market has grown considerably I see very few approaching this level of quality. If you like puzzle games or if you want to be amazed by this game's time mechanics, I highly recommend it!

Limbo

7.8/10

Nice little platformer / Physics puzzle game. Not only must you solve the little physics puzzles in the game  to advance but you must be able to execute the solution.

The game can be dark and scary sometimes but its not too frustrating as the character respawns before the puzzle or event that killed him.

World of Goo

7.5/10

One of the best physics / puzzle game I've played. Usually you have to build some kind of goo contraption which allows you to reach an objective.

Eats Munchies

5/10

Physics based puzzle game. Its not bad but there must be some better puzzle games out there. The game is very short (2-4 hours) depending if you try to complete everything. Most of the time when you can't fully complete a level, its because you don't know how different objects can interact.

There is support for the steam work shop so maybe people have been making better puzzles however.

When I clicked on the steam workshop it opened a browser and not the steam client, I'm not sure if this is normal.
