the mod it's self is sloppy at best, the chambers are simple but hold no real substance, the dialogue is lazy and often has grammar mistakes with no subtitles available for the appalling VA, my recommendation, a waste of Gigabytes and not worth installing

It is a shame because I could tell that genuine effort and work went into this. The main concept of this being a showcase of various new mechanics and how they could be used, for others to get inspired is pretty cool. And there is quite the large array of mechanics. Gel gun, Gravity gun, Fizzle gun, Time gun, Air vents, laser reflecting gel, zero gravity, (momentum?). The work to make the various places your in feel part of the portal universe is done well too. But.... the gameplay....

Straight up, tests in this mod are made to annoy you. You will never feel an 'ah ha' moment in this whole mod. There are WAY too many red herrings. The point of test chambers is not to ACTIVELY try and trick the player. At that point it's no longer a puzzle but a riddle. In fact there's multiple chambers with the answer being to not do the puzzle but find some obscure way to leave it. There is no greater feeling of disappointment when I open a Walkthough and see that the solution was not to do the ♥♥♥♥♥♥♥ puzzle. Also a maze might be considered a puzzle but it is not a fun thing to do. much less TWICE. There where SOME puzzles I didn't mind but they were few and FAR between.

The story was not really all that interesting to me but I was more clocked out due to the nonsensical puzzles so I wasn't really interested in the whole tie in with portal 2. What I do remember made me feel like it was an afterthought.

So the mod had potential and there was passion in it, but it needed to look at what makes portal, or rather puzzle solving in general fun.

This mod is so ass, there's Workshop maps better than this mod. Do not play it, it's so janky that makes you think it was made by a 10-year old.
By the way, lower the volume immediatelly after opening the game if you still want to try it because that intro IS SO ♥♥♥♥♥♥♥ LOUD that it ruined my mood even before I started playing it.

I was going to make this an actual negative review because this game pushed me to the point of having a headache due to its "quality" but I made the doors orange and everything became okay again.

Its not a bad mod for portal 2 in my opinion, but SOME puzzles for sure require more knowledge than an average player
The different guns make for some neat puzzles and ideas and the enviroments are pretty portal esc. Does a great job at feeling like a bigger more expansive version of the Aperature facility. My only suggestion is to add subtitles and make it more apparent where youre supposed to go.

all in all, 7/10 id say
Good, but could be better (also bc of ai voices)
