[WIP] [WIP] [WIP] Experimental Challenge
Alright, here's a screenshot:
And sorry, i cannot help you in the actual fixing as i am not a mapper (i just test and provide feedback!)
EDIT: though you could just make it non-portable surface (black tiles) behind to cover up the back, it does not need to be fancy. If you were following a ruined aperture theme you could have it as a view to the outside test chambers, but you aren't; your following clean, modern aperture. I also noticed on my second play through that something falls behind the turrets as you first walk in. If it is not a glitch then i would remove it as it does not follow through with the new-aperture theme. here's a screenshot:
If you do decide to keep it then fill the void behind this panel as well.
SO you ment gaps between dirps, nothing really crucial, but I'll fix it.
As for the balls, I was aiming for some sort of mechanical failure when entering the test room. I'll get that worked on to have it make a little more sense. With a little more audio indication.
btw I couldn't help noticeing your running a little older map (I'm thinking v1.3) , so you might find more problems with that particular version than the current released version. Not that it severly matters. But it can help with acuracy on feedback.
VDC User PageHmm...you might be right...I'll be sure to take your next uPdate and see if I can help any more.
The hiding the button process will be the most complicated thing I've done yet, and is going to look neat!
EDIT: This is a first. it worked on the first try! 
VDC User PageIs there anything else that would need attention before I update?
VDC User PageUPDATE!!

Great map, very creative! But the music sucks, doesn?t it? 
good, i will be sure to pick up this update as soon as possible. I havent experienced the sound effects for the cube dump yet, but i think it would add more to have a GLaDOS voice over for example, have her say"oops", or "that wasnt suppoesd to happen".In the mean time, while you r not working on this map, i would like to see you design a map where on of the main puzzle elements is deliberate "pushing." I have yet to see a map on thinking with portals that uses this as a deliberate solution. let me know.
edit: Ok....second play through...almost perfect! Balls are good and all voids are filled.
FIX: propulsion gel goes through the ramp when it is raised. it does not affect the amount of gel on the ramp, but you can see gel in the area under the ramp (perfectionism!!!)
FIX: You made obstacle panel unportable. This makes all gel and the panel itself obselete. You can simply use the gel in-front of the panel, and still make the jump. Suggestions: Make the ramp further/farther away.
FIX: You should die if you jump off the ramp and it is not fully up. As said in a previous post: "Think before you act"
That is all.
I'll see what I could do to fix this, this will require some redesign to how to get the extra height on the ramp.
everything else will be as well
VDC User PageSO far their is much more risk for the jump, cut the music out, carfully added some portal sufaces where they can't break the map, and removed some obsolete obsticles.
If you can think of anything else that could be a problem(or already is) post it.
Thank you guys for your feedback!
