Really epic

wow，two different dialogs

i did the same thing xD

I did the same lol, but I think there is no "wrong" solution because this game has so many solutions and at the beginning I thought that I did in that chamber was right

This is precisely the same solution I came up with, once I saw the door opening and closing and figured out I needed to destroy the cube to open it after crossing.

You have to "remember" where exactly you put down the cube in the past

Well, how couldnt I have seen that too! I think I did exactly the same, just with the unnecessary extra step to go back to the past with the future cube...

Holy shit nice lol. I have in fact found ANOTHER wrong way to solve this chamber, I might have to upload it later as well (actually TWO other solutions if you count just abusing air strafing to skip the entire puzzle by coming out of the ground near the exit and then landing on the exit platform, but that's not the most interesting - but there's another exploit I found as well.)

thats close to the same thing I did, instead of using the time portal to change the location of the present cube, i just shot mine out of the angled portal at the exit, so after I launched myself across in the future i could move the present cube, destroying the future one, just as you did here. Its all about destroying the future box, u just did it differently, honestly smarter than I did.

Oh cool! I actually came up with a different wrong solution that also triggered this dialogue. Not sure how to do it the "right" way, then...
