this is no doubt the hardest puzzle. been trying to solve this a whole day

put this off for a long time but finally gave it a go and it was a lot of fun

Took a while, but I got there. Great puzzle.

Excellent! :D

GREAT LEVEL!

I loved this one. One of those where a couple elements of the puzzle make absolutely no sense at first, but then you realize all of a sudden exactly what you have to do and the puzzle seems ingenious.

One thing that still makes no sense to me is why there are two ladders out of the room with the jammed fan. Also, the rewind function stopped working for me past the point where I passed through a purple barrier. That's probably Croteam's fault though.

Another comment mentions the blue laser being pointless, and that's probably true in terms of the functionality of the puzzle, but the purple barrier guarding access to the pressure plate that turns it on was an early obstacle for me, and also gave me a bit of a hint as to how to solve the rest of the puzzle.

Overall great idea and level. The blue laser part is pretty straightforward and mostly just for symmetry with the red one and doesn't really serve much purpose. Removing it would hardly affect this level at all.

@Benzolamps I have just noticed your fix. That should do it. Well done ;)

@MMz Did you put the cube here? https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=3469022287

Hello, it is possible to break v15 Apr @ 12:37pm

1/ Take the cube from the red section
2/ Bring it to the blue horizontal fan section
3/ Drop the cube where the blue laser is passing by
4/ Go in the area where there is a vertical fan where the blue laser is passing
5/ Rub the wall so you don't fly yet
6/ Pick up the cube and bring it up
7/ Drop the cube on the vertical fan
8/ When the fan bring the cube low enough, jump on the cube lifted by the fan
9/ When the cube is high enough, jump on the geometry toward the goal
10/ From there, jump in the final area and pick up the tetromino

Hope it will help ;)

Awesome level
