Can't rate as an outsider but can post this comment. Very good! Could use a little polish, specifically in these areas:

-Right click to simply drop item like in Source Engine (which I know this is based on, I saw that Cave Johnson reference ;) ) 

-Keep the physics on the box while you're holding it. If it exceeds a certain distance from where it should be while you're holding it, it should exit your hand, like in Source. Don't worry about physics bugs, they can be incredibly funny which would actually kinda fit the tone you are going for here. 

-Glass should be more obvious. Give them scratches or a little less transparency or something. 

Now, on to the positives:

-Incredibly clever! A very interesting usage of the theme; feels like I'm an evil saboteur ruining some poor soul's Portal speedrun XD

-Portal reference ;)

-Custom assets are always refreshing. Visual quality wasn't bad either (although some antialiasing would have been nice).

I have a question. What engine did you use to create this game? I've never seen an engine that spits out a pure executable like that except for a decade-old demoscene engine (not even a game engine really). 

Controls are a bit buggy but I was already hyped after reading your pitch, still loved my time with it! Love the visuals and atmosphere yo

I have a latency of one second, which is a bit annoying. But other than that the game is very nice

I wasn’t able to get past the second chamber (the trajectory on the jump pads for me overshot), but pretty fun from what I did manage to play. Kind of like Portal, except you’re purposefully getting stuck.

Neat concept with with lots of fun cube homicide.

Great game, I love it! I really enjoyed playing it! Good job!

I sadly can't get through the first chamber :(

I throwed, pushed and glitched the cube through the window. I even throuwed it through the door, but the game doesn't say i did it :(

But that what i have seen was good. Here a little thing that i noiticed: When you look behind you in the hallway before the fisrst chamber you can't see anything. I shouldn't took to long to place a usless door behind the player so that it doesn't look's like he came from the chamber.

great game found some cool glitches

I played it for hours

Good concept, fits the theme.
Some minor thoughts:
- nice twisted puzzles
- solid visuals and intro
- sometimes the buttons not react perfectly
- control while in the air is little bit confusing
- some SFX would be nice

The aesthetic of legally distinct Aperture is really cool (my favorite part was how the opening letter was signed 'Cavern Johnson'), and the idea of turning unintentional softlocks into the main mechanic is very interesting and ends up being a lot of fun. The visuals in general are quite polished, but one thing I would like to touch on is the gameplay - I ended up softlocking Chamber 2 both by throwing both cubes out the observation window and by throwing one cube through the door.

Overall, great job! This is one of the most polished games I've played so far.

very cool!

Amazing, a little bit too dark but apart from that one of the best games I have played so far :D

Not many words, just good!

Really original idea! It's a bit tricky to complete the levels, but very enjoyable
