For those of you who liked Portal (a.k.a. Everybody...)

I found this game while lurking on Newgrounds which employs a strange concept; I'll try to explain it, but it's much better experienced firsthand.
Basically, you and the walls are colored black, while movable areas are colored white. However, hit the left shift button, and you'll "flip" around, and the colors are reversed; you are now white (lol racism) and all white blocks are now obstacles, while black areas are empty. Sounds a lot more complicated on paper than it actually is.
The author also pays tribute to Portal throughout the game, and it's just as addicting, but incredibly short. He says he's willing to make a sequel, though.

Very interesting game. The timer is a lie!

That was awesome. Great find!

hey, good find. +rep

That was fun :} Killed a few minutes of boring class time.

Nice find +rep, too bad it was so short. Hopefully he's really going to make a sequel :P

I played this a while ago. Freaky game.

Very nice. Too short though...

Pretty awesome, I loved it. +rep for you!:awesome:

It's called "Shift" and I found this a few hours ago using Stumble! Wow =)
