GLaDOS decided to test your abilities even further. She's given you a portalgun for this test, but she altered the gun to make portals unstable. They will only allow someone or something to pass through once before one side collapses.

Good luck solving this test. You'll need it.

Difficulty estimated: Medium (6/10)
---[ Scientific explaination ]-------------------------
Portals consume some energy to maintain themselves. Normally when a portalgun fires a portal, it is set to draw energy from the light caught on surfaces. This is why a portal will fire on a white surface, but not on a black. By changing the energy used to fire a portal from the gun, it is possible to make the portal unstable. With very little energy, a portal will collapse after a certain time, or, as with this test, with just enough energy to sustain itself, it will collapse as soon as someone or something passes through.

Ah, yeah that must be it, given that Ihaven't updated. :D

I know it's the style. It was an early complaint when the style was new and teamspen reduced the volume of that sound. Maybe in the version you're using it was back to the very loud noise again for some reason.

Thanks for your kind words Toncica. Glad it brought you this. I can't comment on the sound as its not within my control. To my knowledge, it is the same as "Access Granted". But maybe its a combination between using that style and the vanishing portals.

This one totally exceeded my expectations and I had to think hard for a while. It has to be the finest logic I've seen in your maps. The joke's on me for underestimating the puzzle part. Vanishing portals were an interesting twist but inconsistent in my case, maybe that behavior is changed by quick loading or contact with cubes. Fun puzzle to figure out, only the thunderous sound of lights going on and off was very distressing. I think the loudness got accidentally increased in your version. With headphones on it seemed to drill holes into my eardrums.

Thanks josepezdj, that means a lot to me. I'm glad you liked it so much.

AWESOME map! :D Very very good one LP! I don't know how you imagined this new mechanic but it's amazingly funny, mate! I got a bit annoyed a couple of times because of losing my portals, but nothing serious :P I thought for a moment that maybe if I exchanged my portals from position, blue where orange was and viceversa, I could keep it in the desired place, but noooo, the same one was erased all the time

I loved the puzzles you thought out with this idea, very much! So I REALLY hope to see more of this soon! ;)

Thanks Stormsend. Glad you like it, and even more pleased you like the visuals of the map. Makes me even more want to continue building aesthetic chambers. :)

Very nice. That closing portal threw me at first. A great additional element. As usual I dallied around looking at the sights. Beautifully built. My real confusion began when I got past the orange funnel. I had to decide which cube went where to get to the exit. I replayed that section several times before it began to gel. This is a favorite. I guess because I consider it difficult but I managed to get it. And it looks great. Thank you for all the work. Enjoyed tremendously.

Hi Ivo, I didn't take into account any bugs or glitches regarding the mechanics. The puzzle is entirely solvable depending on the portals fizzling. In fact, in all my testing they fizzled. As for the faithplate, I am aware of it being possible to bypass, but if I publish the map now, a new version is created. This keeps me from updating this one.

Cool test, although I didn't understand the mechanic at first. I mean I read somewhere that TeamSpen has made a BEE2 element with which help your portals fizzle when you pass through them, but I at one point I found out that if you (or an object) pass through an orange portal, it doesn't fizzle. Does this have to happen? There's also that faith plate, which you can glitch by moving in mid-air and preventing it from catapulting you into the fizzler. not that it made the test easier or something, the trigger_catapult just does that if it doesn't launch the player fast enough (which is very often with the puzzlemaker). Not that hard as it might seem at first and it's quite fun. Thumbs up!
