SOOOO excited for Portal 2

Recently been delving into the original Portal, which was released in 2007. Great game, almost have it beat and I started it a few days ago. I could do it all in one day if I were back into the lazy days of in between college and first job and there was just endless time.
This game being short in length makes you feel like you zoomed through and you're so clever and smart, but I do hope Portal 2 will be longer.
There was one section where there was a long fall and i had to put a blue portal above the fall on a "usable platform" and then a orange one below. Jump into it and endlessly fall over and over and over. so cool.
or you can put it on two adjacent walls and start running. it's like an endless hall.
those lazer-bots are annoying as hell though. although they have zero peripheral vision and can easily be picked up from behind and tossed against the wall. even if you do it gently, they topple over and die.
if you pick up the brick and nudge against them they fall over too.
level...16 i think. i never did figure out what that orange hole was for. it opens and closes periodically.
there was a clump of bricks under it. i thought at first you were supposed to reverse gravity somehow since it's on the ceiling. but theres no where on that level with a high enough fall to hit it with enough force. so.... i got the end without even using it. they just put it there to mess with your mind!
i hope also that portal 2 is more difficult and doesn't get too involved with its story line. i don't want a story, just the puzzles. i like my brain teased.
