Honestly, I got so frustrated that I ended up removing this from my queue. I might try again another time.

Dear Robot Han.
At the entrance of the four holes, there is a different arrangement of the optical piece.
The pattern will be able to distinguish between each hole.
For example, if the hole is deep, the optical piece is made vertically.
In addition, depending on the number of light pieces, will come visible order.

Challenging but fun.
My biggest problem was getting lost between the four holes when trying to get from one point to another.

nevermind, i sloved it without the companion cube

Ive dont everything except for find the secret companion cube, I have a feeling i know where it is, but idk how to get to it. Its driving me crazy!

その最初のスイッチの良い仕事。これは偉大なチャンバである。

Looks like you moved the first button, based on the screenshot, which would solve the problem. ;-)

Dear DeathWish808.
Thank you for your advice.
In my poor technique, the action could not be reproduced.
Time thinking and behavior of the platform is concerned, I tried to put a little facelift.

I skipped the whole puzzle. Stood on the first button just long enough to not kill the cube and got through. Placed portal on ceiling and went into exit area and shot portal on floor under cube and done.] I also went back and did it the correct way since obviously that wasn't intended. I would just get rid of the funnel and fizzler and just put a cube there without the dropper and put a pedestal button instead of pressure button to activate a fizzler to kill it or make the floor dropand close back up. Just a suggestion.

Dear KIRBYTIME.
Enjoy in the test, thank you.

私はこれを正常に完了しました。この時は非常に良いです。

心配しないでください、私はあなたがマップを何度もテストしていると確信しています。私はそれを完了することはできません

Dear KIRBYTIME.
I can read English is not good at Japanese.
I may not be able to understand exactly what the question.
It is the answer on that based on the above.
If you just want to clear, this puzzle is possible by going through a number of steps.
However, to get to the exit to find the hidden companion cube, you need to use the information visible to the limit the field of view.
To test dozens of times the puzzle that I made, I have been repeatedly adjusted.
Does not require quick action, I prefer the structure that focuses on solving the mystery and discovery, if anything.
I have been exposed to the workshop, which was determined by the work they create, and the fun myself.
This answer, I would match the intent of the question?

Just one question. Have you managed to finish the puzzle yourself? I'm finding it difficult to do so.
