This is the best flash I've played in a very, very long time. Over the period of a few days I eventually beat this, and I'm very impressed. This was very challenging.
I can't compare you to the Valve "Portal", though I'm planning on getting the Orange Box soon, so judged by the standards simply of that of a game, this is excellent. I truly had fun, and a pretty good smug satisfaction after I beat it.
Couple bugs I saw. One, this doesn't really matter, but sometimes you'll fly through the wall above the exit door when you leave. Another, this may be on purpose, but boxes don't block the portal (trying to be vague, I don't want to give it away if it's purposeful).
Great game, great job.
Oh, and kudos on the G-Man appearance. Just saw that today :)
you have stolen my idea for a game. you shall burn in hell! (also the main character is a girl.) also if you make a sequel please include apeture science, maybe some halflife quotes because portal is based in the half life world.
All my 5 R Belong 2 this!!!
This game was absolutely insane. Almost dead on with the gameplay compared to the real thing. Only problem I had was spotty portal placement, such as I could try and snap a portal up on to a wall where it was possible only to have it not produce one and cause, at times, a lot of frustration and the loss of a level. Other than that, it was excellent. Kudos to you guys. I'd dare to say that this is the best game to come out of the Portal.
Oh, one more thing. You claimed that level 35, if I'm not mistaken, was supposed to be frustrating. I enjoyed that level most of all. It was loads of fun.
Keep on with games like this. You guys are the reason why people come to Newgrounds. You provide quality entertainment for everyone. Good job.
