Difficulty: Medium, Hard. Only for skilled Portal players.
Eventually, I did this map. As you can see this is my third map in series of "Brainteaser" hard maps. Don't forget to save and don't give up! =) I'm sure that some people will fail this test that's why I'll put passing of this map on youtube after few days.
