Oh, I remember this :)

Oh boy this chamber. Is this a reupload?

Ha true, I don't need that tip anymore. Haru pointed out some other small problems with the puzzle so I do plan on updating this somewhat soon, and I should be able to remove most of the grating. Though with the history of this puzzle, I'll probably will have to publish it under a new link again.

Fun map! Maybe slightly architecturally overengineered (and as 可砸 pointed out, for those of us with low graphics settings the long sightlines through multiple layers of grating to the standard-cube-respawning suface risked obscurity ), but the map has some very nice subtleties and I enjoyed solving it quite a bit. I also have no idea what the "important" note in the description means. Thumbs up.

I thought I was close after ages to get up to the final move getting both cubes past the jail bars but I would not have figured that out without watching the playthrough. Amazing puzzle.

Also, the tutorial room wasn't very reliable for me. I'm not a fan of this method. I chose to solve this puzzle in another way.Seems that my previous message(have deleted) was based on an old version.NM.

Finally,I found something very minor and I'm not sure if it will affect the game's progression.

I enjoyed most of the puzzles, and my favorite part was the way you traverse between both sides , including how you respawn the regular cube.My only complaint was that the large panel was devilishly challenging. It took me a long time to figure out that I could open a portal from a certain position, which was quite frustrating,well I didn't realize that.The ending was interesting. I almost knew how the ending was set up as soon as I saw the grating surface on the ground. So compared with that,it was more tough to bring them out .
