I just finished this game and it's awsome, keeps you going for hours.
And i too found a glich or something, when you fall down with enough height on the blue lazers you end up in another part of the level.
i have played portal (well portal 2) and i have never seen such a well crafted game. However, the part with the energy balls is uncalled for. can't you skip that?
I didn't like it that much but...
Gave it a 9 cuz I have no idea how to make a flash game/vid, so the effort you actually put it is more than enough for a high rating :)
It even made me look up the real one for the 360, I made it to level 38 but now im stuck. errrrr i'll get you eventually damn drones!
Its good game, however its pretty hard so I couldn't really finish it. It stacks up well to the real Portal. Now you are thinking with Portals.
