try to us the lazer to activate all 4 detectors at the same time

I got the two cubes, but I have no idea about the sense of the detectors, because there are a lot of symbols and I can't find the belonging mechanisms.

:) fixed again I think :P

...must...resist...killing...turrets...

thats a nice find fixing it. Thanks a lot for the feedback

But, but... if I walk to the button now the turrets will shoot me. That's dangerous! What were you thinking? Those turrets need to die NOW! ;)

To be honest, I had a glimpse of this idea even on the first try. Then it just vanished until your update forced me to think of it again. Brains work in strange ways.

hehe, dammit I thought the turrets would gun you down when pushing the button. I've fixed that now I think. I added the button to avoid the repetition, before you had to completet the lazer puzzle twice. Thanks toncica nice vid.

The first time you probably have to finish it the hard way. It is challenging but not particularly hard to figure out. If you take a good look you can even plan ahead, avoid the repetition and simply skip the laser relay puzzle in the middle floor.

Difficulty 9/10
Fun 9/10

Great layered map. The continuity of the laser cubes throughout the whole map was brilliant. The complex use of lasers and light funnels, all brilliant and provide a hugely satisfying challenging map.

Could have been slightly clearer that all 4 switches are needed to advance but other than that one of the best maps I have played that brings out the essence of the Portal series.

I actually dislike that a bit too I think Ill change it

I liked the puzzle at the bottom to get to the top, and the puzzle at the top to get to the exit a lot. The part in between involved too much repetition for my liking, but other than that, great map!

Thanks alot, I hope you enjoyed it :)

Holy crap! That was the hardest puzzle I've ever had. Excellent work.

That took me ages!
