Simple Logic (HARD)

Great set of chambers. The logic was simple. I liked that you could go back to the previous chambers.

Yay, sinally finished it. Kinda figured while half asleep that the last switch had to reverse the polarity of the tractor beam. didnt seem possible otherwise and it explained why there was a timer on the switch So tested out my theory and yep... i was right. so no problems after that. Very tricky. Got to say this was the toughest logic puzzle ive done by a long way. Been on it almost 4 years lol.

Finally worked out how to get to the highest passage in the third section. using the light bridge from the second section. Now I have a chasm to cross and it seems I need some blue gel down the bottom. Seems impossible to do though.
So close to the end now. Just 1 puzzle to go it seems.
Guess I need to think about this some more...

Ive been recommending this map to everyone I know who plays portal. Darned hardest map I have ever played. Some of the manouvres take a bit of skill to pull off, but I think it's necessary most of the time to make a tricky puzzle. Nothing in this level requires too much skill IMO.
Well done error0x0 !

Couldnt edit so I reposted.

I first tried this map in 2012 and got as far as the third room, but couldnt work out how to get to the passage at height 4 above where you enter the third room. Well... it occurred to me the other night was I wa lying in bed pondering this level. So next day I tried it out, and after a bit of mucking about trying to pull off the manouvre I finally did it.
You need to bounce with gel on the platform diametrically opposite to get height then bounce all the way over

So then I was able to open the passage back into room 2.
I figured this was there for a reason, and remembering how in room 2 how I needed to go back to room 1 to get a prism cube, I figured there was probably something in room 2 that I need. I suspect I have to make some use pf the platform beam and somehow get gel on it to reach the really high passage.

@vladesch, Congratulations! Thanks for the playing this map! Please try my other maps (if you haven't done them before), especially Interference (HARD). And please fix the second spoiler in your comment;)

@h99pilot, thank you!

I love your maps. I recently replayed Interference (hard) which has the most complex twists of all maps i have played. Knowing the solution does not diminish the technique of the puzzle. I just replayed this map and was once again scratching my head at the gel room until that ah ha moment. I cant believe more people havent played this since I played it last year in April. I have played your other maps, some to completion and some to the point where I know the solution but my skill at certain manuevers is lacking.I look forward to any of your new creations and once again Bravo !

@h99pilot, if you have enjoyed it, try my other hard maps! Thanks for your feedback!

Now that was fun !!! And (HARD) !!!Somehow I thought once I made it through the top passage in the gel room I would be done... but NOT. Thanx for a real challenge.
