This is how I solved it: https://youtu.be/S6l3mbniEAM

In your very first reply you said that the player is supposed to fling the CUBE into the funnel instead of himself?! I see no other way but to prepare the funnel portal by flinging into the funnel yourself. Well, nevermind.
When I eventually had that map solved I was wondering where the exit is and needed a minute to find it XD It's a bit "hidden" imo ^^

After solving this map I read the comments. Very confusing. I did not do any cube tossing or use the upstairs button or switch off the light bridge. Thanks for your work.

Yup, the intended solution is more interesting. Keep 'em coming, please!

Nice map. Sometimes, when my brain hurts, it's more fun to play an easier map, especially when it still has a clever solution. BTW, I didn't use the upstairs button either, although I could see the intended use. With those portable surfaces, there was no need. I'm going to run through it again and see if I can do it the intended way.

Great map! I couldn't see how I was going to get to the exit until it opened. Could you put a mark by the bridge?

:)

I'll upload the unedited for you demon, but will mark it as unlisted so it doesn't bother people's sub feeds

Oh it's okay, I'd appreciate it but I'm not sure other people would :P It's always useful to see blind playthroughs of my maps so I can see where you look and which bits you find confusing/intuitive, good/bad, easy/hard, etc. But don't worry, I'll be happy with just the edited version :)

I can upload an "un-edited" version if you like as well, I still have the original footage but it's a lot of silence and doing the same thing over and over again

Ah, no worries, I can see why you gave up! :) I hope you enjoyed Illuminet Tenebras despite it taking you a while, I look forward to the video - would've liked to see the unedited version :P I'm trying to make my maps harder recently, so please do let me know if you found it overly difficult and I'll make sure to adjust the difficulty accordingly for future tests

Nope - In all honesty I started that and just abandoned it (sorry). It was the one with the funny name with the faith plates and Light bridge. Edited it earler and cut out about 20-25 minutes of me just wondering what the hell i needed to do!

@nockscitney Hey, thanks Nock! Was it Solar Energy you had trouble with? That one is highly temperamental...

In comparison to the "Hellish" time I had with one of your maps last night (look to my YT channel later in the week) this one seemed to flow pretty well and didn't trouble me too much. Played on my stream today (https://www.twitch.tv/videos/128833166) :)

@libbybapa Thanks! Yeah no worries, I appreciate it! I hope you look forward to the maps getting better later on :P

@libbybapa Thanks! Yeah I don't like it either, but I no longer have the files on my computer to edit. A lot of these old tests have things like that in them, since I was still getting to grips with how to make good tests :/

Brilliant puzzle. It took me a while to discover that I could shoot a portal from up there to down there, but once I'd done that, worked out what the button upstairs did..... hold on.... just did a re-run: I didn't use the button upstairs, so guess I completed it by an unintended method: walk with cube into light bridge room, shoot portals on wall hi/lo and jump onto light bridge with cube, place cube in tractor beam and walk out of the room - intended method/I didn't think you did red herrings? The rest I believe I did as intended.

yay!

@jandlml Thank you very much indeed for all the lovely comments, glad you had fun! :D Don't worry, more tests are always on the way :)

well i think i played just about all of your maps. i really enjoyed them. keep making them

i didnt think i would be able to solve this one but i did. nice map!

Easy, yet satisfying .

LOL that's funny. The last time I tried this map a few months ago, I gave up on it for that time (even though I solved it before). This time, first try, got it virtually instantly. :P

Nice simple logic map.

I didn't find it easy but it was fun to solve. Many failed jumps and numerous fizzled cubes later I made it. Very nice looking chamber. Lots of visibility. I like. Thanks.

Timing? It's easier than it looks. Also I found the button to open the exit very troubling because I didn't know it would also create a bridge. I think it would be better to leave the exit open and tie the bridge to the button exclusively. Otherwise, nice chamber, although easy.

@quaternary Yes, that's right! That's part of the intended solution... Sorry that this chamber isn't exactly my best, but oh well...

Are you supposed to be able to shoot into the upper level from the platform with the button that controls the fizzler?

Thanks Sagittarius, I was going to put a line connecting those panels to the button but it looked too messy... :)

Great puzzle altough i had a hell of thinking first, how the hell a i going to cross that water? :D

@chyborg. No, that's absolutely great! Thanks! :)

I've made a remix of this map. I hope you don't mind.

Didn't take me long to solve at all, but it was clever, and that's never a bad thing :)

Here is probably another solution you can delete. I'll try solving it another way next time. ;)

@chyborg Oh, sorry. Yes, thanks, I didn't quite realise that you could snipe that portalable surface from the upper level. I'll add glass or something. Also didn't think about flinging yourself into the funnel, you were supposed to fling the cube into the funnel .
Well done for finding those though, it's helpful. :) If you like, you could try my map Pure Logic, or Indirect, which I'm more happy with.

Will you make changes to prevent my solution? I think with a few tweaks it can a be good, challenging map.
