Don't sweat it too much, man. Like I said, I still get to play the rest of it, and I figured what you revealed wasn't the be-all, end-all revelation to this game, so it's all good. I've accidentally revealed spoilers online, too. I commented on one of the Nostalgia Critic's videos about The Last Airbender TV show, and as I tried to defend what I thought was a pretty tame comment not revealing anything I found spoiler-ish about a certain swamp episode in the first season, I earthbended myself a nice hole by explaining what I thought were actually spoilers, thereby revealing those spoilers in the process. So, we'll chalk this up to karma giving me a small bit of payback, and I admit I've done a lot worse than anything you just did. lol
I wonder how much I would enjoy the challenge you say Braid presents. I do love puzzle games, but I got stuck in the Portal demo, so that doesn't make me overconfident about my own abilities. lol I love Prince of Persia: The Sands of Time's puzzles in that same vein, but that was an action game where the puzzles were somewhat secondary. The deconstruction of gaming narrative sounds intriguing though, and if you say it's fun and challenging, I believe you, so on my Wishlist it stays, and I will continue to consider buying it, especially if it goes on sale again.
As for multiplayer, my friend Kalei just asked to add me on Steam, so awesome, more friends. I don't know if my laptop could handle something like Battlefield. But while it doesn't seem like my type of thing, apparently Greenman thought the same about it and wound up loving it, plus it's a free game, so I may download DOTA 2 for multiplayer purposes.
