Very extensive, very fun, not to mention addicting. You've created something really unique and made it beyond entertaining. Great job.
Hell this is one of the best...this is as good as it gets...only thing is that it's easy and maby some more lvls wouldn't hurt but any way it's cool 5/5.
A phenomenal flash game!
This game is absolutely amazing! I cannot even begin to imagine the coding it took to create a game of this calibre. I really think this is one of the best flash games I have played. I also love the way you kept it exactly the way the game is. It is very simple and clean, just like the game by Valve is. I think you guys did an amazing job and I will definitely be playing this game for hours. You guys need to start making a second one because everyone knows that the biggest complaint with Portal was the lack of levels. I think you guys should beat Valve to the second one!
Really amazing game! 10/10 for sure.
Captures Essence of Real Game
This is really well, done. The game is very fun, and easy to learn. It provides a good challenge, especially the last three levels. I have also played the real game, and this one really captures the essence of it. Well done, I hope there will be more to come!
It won't play, none of the butons work. But i'm sure it is just me, so I'll rate it on the hype it's recieved.
