Very nice map with good logic and reuse! Favorited

very well designed, this one is really upgrade to toggle.

Really neat map! I wandered around in circles a lot the first time, then played it again to try to get a more compact solution; I'm still not sure if I did it 100% efficiently, but regardless I enjoyed thinking through the logic of how to get all the portal connections I needed. Big thumbs up!

Great puzzle! I walked in circles for a considerable amount of time before I noticed the extra shelf to pass the goo one direction (above the angle panels)! I haven't played much lately and need to remember to be more observant! Regardless, great logic!

Fun chamber!

I concur with @bullfrog. Thanks for changing it to "medium". It makes us mere mortals feel not so bad ; )

Good update and thanks for changing the difficulty rating; at least @E L Y T R O N and I don't feel quite so stupid ;)

Brilliant puzzle, another and added to favourites. I believe there are slight variations in the way you can solve it, but every element all the key moves are used - this is the way I solved it: intended solution ?

Update: Fixed Dark Rozen's exploit and changed the difficulty rating :P

This puzzle is brilliant, definite I’ll add this to my favourites, once you’ve done the update to prevent Dark Rozen’s exploit.
As a few others have effectively said: “Easy-Medium” are you having a laugh? There are two rail platforms in each of the three rooms, which make 32 possible combinations of the maps portal surface layout, apart from the one in the exit room. Also, there is a laser in each of the three rooms that can be blocked, or not, by either of the rail platforms in that room. Also, there is a light bridge in two of the three rooms, that can be blocked, or not, by either of the rail platforms in that room – etc. etc. etc. come on, it’s gotta be a medium at least ;)

finally beat it OMG. "easy-medium" is just insulting and cruel!

This does a lot more than boggle my mind...it is mush. Thanks for making me feel stupid

@Dark Rozen hmm, I'll have to think about how to fix that one...

I broke it https://www.youtube.com/watch?v=E6sLzIX7Nf4

Update: Fixed an exploit.

This is a really cool puzzle. The thing I like about it most is its flow.
First it starts by solving each section individually. I got toward the end of the 3rd section and was confronted with the actual win condition at the end which made me rethink how to use all sections together.

probably,ive had weird problems over the years

@jandlml the surface won't let you put a portal on it? Strange, do you think it's just on your end?

excellent map! even though i cant put a portal on that surface

haha well i got to the portal surface across from the door , i have the bridge but the surface isnt let me put a portal on it. not sure why. im going to noclip across

i dont know why steam keeps changing how to take pictures. does anyone know how to copy a screenshot. it was perfect before

oh my gosh not again, an easy map that i just am having so much trouble with. i keep going back and forth. i know what i need but i cant figure out how to get the bridge and the laser right

very nice, better than toggle

Nice puzzle,tricky but clever,after you got the first LB ,it ended so quickly...

That difficulty rating is oddly specific and relatable. You ok?

Oh my god this took a bit! Even after beating it, I replayed it about 3 times to fully understand what I did was enforced. I would argue to me it's Medium. I found it a little overwhelming myself, although not a knock against the actual puzzle.

This was great! I've been craving for a track platform+light-bridge for a long time. So I'm happy that the combo was fully used. I was also surprised by the middle room. Every time I got stuck it was due to under-estimating the middle room's usefulness. Great work, easy fav!

Pretty interesting. Kept forgetting about lasers crossing the rooms.

Very clean
