I have now updated the chamber and hopefully removed all traps. Thanks for pointing them out Gorix and Barbos. The solution is almost the same.

Bisqwit, you will be happy to know that buttons now have antlines wherever possible. Test Chamber Junkie, I detected a tiny hint of frustration in your video when you worked with the laser puzzle in the ceiling, so I decided to make some small changes there to make it a little bit easier!

I got stuck in a room with goo and button. Rated down.
Please, test your maps for stuck occasion

Thanks TCJ for the kind words and the excellent walkthrough!
Bisqwit and Gorix, thanks for your valuable input. I am sorry for the trap. I know about it, but I have yet to figure out how to fix it without breaking the puzzle. For now, use F6/F7 to save/load before entering! As for the signs, what can I say - I like them! But I'll think about it.

If you get stuck on this map watch this helpful vid: lord_dhaf's- Styx
Excellent map! Keep up the good work!

I could not solve this puzzle. I can confirm what Gorix commented below, though. In fact, it's pretty much the only thing I was able to achieve. Scouting around with noclip, I will say this puzzle is too damn huge. Way too many elements. Also the lack of antlines (preferring to use signages) was a factor that resulted in a lot of "hunt for sign X" which is frankly not fun at all. So, here's my annotated demo of the blind playing. http://bisqwit.iki.fi/kala/ptal2/styx-dha-blind-by-bisqwit.zip The total runtime is about 29 minutes.

You can get stuck in the room opened by the button in the entrance...I mean literally stuck in there because you won't be able to open the false wall if you place the relfection cube on the button there. How is it possible for someone get out of there?

Thanks for the kind words! I too like a puzzle where the solution is a little bit obscured.

Wow! Just solved your puzzle, It was really challenging but I feel extremely satisfied having now completed it. I got completely stuck on the first room, I had to sleep on it but came back the next day and solved it. I liked it because the puzzle solutions weren't obvious like they are in some puzzles.

Small update: Added some lights and removed the cube that wasn't really needed.

Thanks for your kind words!

It looked very difficult to solve in some places. That only added to the satisfaction at the end. Some very nice ideas. http://youtu.be/NpCzjvq5hWQ

A well-made test, i love the soloution about getting to the sphere-fizzler-button.
Also the room with the first laser switch is really dark, you might want to put some light there.
all in all it was a cool time.taking chamber but there wasn´t really this aha-moment.

Hello! I test it again, but this time the exit door worked as intended! I was sad to let the companion out there, but at least, it was not alone anymore!

Fatalys93, I'll give you (and anyone else that get stuck) a hint:
The forcefields on the other side of the river never goes down. That is a fact. But this doesn't mean that you can't bring something useful out of the room...

Is a very good test but i'm stuck in the last part! if i remove the sphere from the bottom at the top of the tunnel the laser for the exit is ON! and then if i put the sphere for the exit...there is the laser XD and i don't understand the use of the three cube in the third chamber (2 laser cube- 1 companion cube) ... WTF? xD

I dont have access to the game until this weekend...I'll test again and come back to you!

You may have found a shortcut! Is there a way to keep the laser field off while using the sphere to open the exit, without using anything from the other side?

Was fun! But...was I suppose to go the the other side? The door was open, the laser field was off with the sphere both times . I went there anyway, and got those , but with no apparent way out with them nor use!
