is there a mod for the in game editor to have colored lights, like green and red?

Having trouble with the second one. Would appreciate a walkthrough please.

I did manage to bug the first part of prelude by shooting a portal back into the initial starting location, using the -chair- again and respectively being stuck to it. I love finding Easter Eggs / Bugs :D

This is awesome! It was easy, but it stumped me a few times, keep up the good work!

I like the concept that you made, I only played the first one yet, but I can say it is easy/medium, I'm going to try the second one now

Very good concept and puzzles. The Multi-Generator is like a fizzler that you can't see through and that doesn't fizzle portals when you pass through it. Excellent job making the puzzles fairly difficult.

I knew there'd be another one!

Agree with TheKanjiWolf. Hardest Chamber(s) I've ever challenged...

Really liking these levels. They force you to think not only in the current space but in the opposite space as well. A lot of fun!
