Braid is loved by all. Journalists love braid, players love braid and hell, even I love Braid. First released on Xbox Live in early August 2008, it was Jonathan Blows debut game, now noted as one of the most successful Indie titles. When games are normally ported to the PC there are two real types of production methods, the cheap re-release and the re-haul. Coming with the PC version of Braid is an in-game editor that allows players to modify both the assets and the levels within the game, which is fantastic extension to the game. Your not just limited to playing your own creations either, by loading others mods or "universes" your $15 purchase just got a ton more value.

-editor : Enable the in-game editor. If you use this command-line option, pressing F11 will open the editor to the level you are currently playing.
You can all expect to see some great things come out from the editor very soon.
**UPDATE** Jonathan Blow has released a small download and a tutorial to help people get started making mods for Braid, which you can find here on ModDB.
