It's an ok test chamber, very basic but I suppose that's to be expected considering that it's your first. The angled panels aren't strictly necessary as the player can jump across from a high portal on either side of the exit door area or a standard vertical portal jump will also do the trick. Perhaps experiment a bit more with the editor, get a feel for what items interact well with each other. The mechanics in here are fine but there are so many more possibilities.

I've got a little collection of chambers going and I'm always interested in feedback on each chamber or the collection as a whole. I'd be grateful if you'd have a look:
