Thank you Pumpkinhead! :D

I very much liked it! Thanks for the link!

Thanks Ze Laughing Dog! The thing of losing the cube, I can't even imagine someone playing my chamber without an angry face, haha

As of now, I haven't completed this test yet, but I will tell you what I think where I am. This is an excellent test chamber. I've had some, "Wow! That was cool/creative!" (You can tell I haven't tried out any other community chambers, I'll add that to my to-do list...) moments, but also some frustration. When you get your portals deleted by one of those door things or lose the cube when you've made quite a lot of progress in the stage, you have to start over, there isn't a way to undo, or get back to where you were quickly. (At least, from what I've expirimented doing anyways...) Other than that, good, fun test!
