Gel...From Scratch!
I finally came up with a puzzle based on anti-conversion gel, which would be much easier to write than conversion gel. 
So wait, which one is the anti conversion gel again?
Aperture Science: We do our science asbestos we can!
It might be black, as non-portable surfaces are.
It will probably be black, since I now have Useless Shiny Gel to make reflective.
Okay, sounds good!

Are you Still working on it? There was long time no progress-update here and it would be very sad if it is discontinued, it's such a great thing!
Don't worry, I haven't. That huge sheet of puzzles I posted in another thread uses the purple gel from this. 
I don't know if it's too much trouble but....
Could you maybe make the 'unused' fourth gel that allowed you to stick to walls and make it's gel dropper too?
I have some really neat ideas for platforming around a 'maze'. But that gel seems more fun than simply portal-ing around the map. I know Valve testers said it be disorientating to players.
BUT
I actually have a basic idea on how to use it effectively, without making you dizzy, and I want to prove why the fourth gel should be in the next game. (Since in the next game the fourth gel would be the only new mechanic)
Also I suggest an interesting idea *sadistic grin* ICE PHYSICS GEL 
If it's possible anyway XD
PS: Make a tutorial for making or at least adding custom gels Plz? :3
That's really hard to do that. It requires particle editing experience.

Well...I'd really rather leave it to someone who can do it without screwing it up lol
A tutorial on adding a pre-made custom gel to hammer is what I meant o.o;;
