Perpetual Corridors

Escape the underground corridors to make your way up to the exit level. This puzzle involves mostly tractor beams and some portal fling. You might find getting the first cube in the first main chamber a bit of a challenge. The timing is slightly tight, but not too strict.

Thanks for playing. This one was a bit complexicated (I guess that's a word I invented), but I tend not to build them like this anymore. As for no evaluation screen, it could be one of Valve's updates. I tore apart the logic control for the elevator instance and found point entities that cause that. But no more since I tweaked them.

I made many dry practice runs before attempting the cube transfer to the button to open the door. I am proud to say I passed the the first chamber on my first real run. No cube loss in first chamber. The second part was easy for me. The third part surprised me. Lost a lot of cubes there due to poor alignment judgement. After leaving thru (I know how to spell " through "...thru is short and easy with good meaning) the exit the screen went black with no evaluation screen.

My favorite room was the last one with the blue funnel. The first required a little timing, but should not be too difficult for most players.

Solving the first room was moderately challenging. However, actually performing it required a lot of F6/F7 to get it just right. The rest of the level was straight-forward puzzliness. Altogether, a very fun and engaging chamber.

I'll have to go back and check that out.

Wow, that first room is crazy! I have no idea how you expected people to solve that but I managed to find a glitch that worked. I was able to get the flip panel to catch the cube as it tried to open and then, after a few tries, it flipped it towards me so I could catch it when it closed. The rest was quite fun, though. :)

Thanks for uploading. I enjoyed watching. As you can see, that last part was a bit tricky. It almost like you have to be in 2 places at the same time. So for the next one in the series, how about blue gel?

Thanks for playing. I'm glad you liked it. There's a sequel coming. Or this might be a new series. Once you get into the hallway, there'll be some separate rooms full of conundrums.

Ok I beat it! lol - However, in the first room - I did not use the button that worked the door at all - not sure if this is intended or not - second funnel puzzle - was interesting with some twists - that last funnel puzzle had me baffled for a few minutes - then I had a "Oh Duh" moment and went on to victory. Thanks for making - I love your maps! Well done again!
