Being stuck home yesterday on account of a stomach bug, I had a great opportunity to immerse myself in Braid for a solid afternoon.  With so many games competing for my time, it's relatively rare I have a large block available to dedicate to just one game, but Braid was totally engrossing.  It's not the longest game, but it delivers a great experience -- particularly if you are into puzzles and time travel (two of my favorite topics).  The "story", such as it is, is kind of interesting as well, told in a very spartan style yet I'm quite interested to see how it all comes together in the end.

It's also the first game in a while with a unique enough control flow that after my long session of it, I was in a kind of trance, seeing every motion I took as some sort of semi-reversible pattern.  Kind of funky, and just showed how into it my brain was.  The first time (that I can recall) having that sort of "out of game" experience was after some Doom 2 all nighters and my brain kept telling me to strafe around all the cars in the parking lot as I stumbled out at 4 AM.

Anyways, Braid is up on XBLA, and it's totally worthwhile.  Check it out.
