Great game!!!! But laggy, invivible bridges and portals are a bit buggy too.
Really good. Got me in the mood for a Portal 3. Fairly difficult too.
Awesome game but i'm getting confused on level 3.
There is no right click menu. you cant change graphical quality. portal the flash version is better to me. the puzzles are a little hrder.
I prefer the 3d portal game that allows two players
