Okay, so. You've made your chamber. You've refined it. You've lit it up. You've completed it. You've published it.
Now just answer some comments and forget all about it, right? I mean, even if you, say, get comments like...
This can't be good. I can't ignore them, now can I?
So, since the main complain seems to be the way you have to adjust the box until it's just right, let's think a bit. What could replace moving the box around...
What about placing portals in different places?
With this in mind, I procceed to move the observation room.
I realize, however, that it is still incredibly hard to actually hit the small target. So I go ahead and decide to place the button in a place where it would be easier to actually see what's going on.
I use a faith plate so that you do not need portals to get up there, and make use of light strips as to avoid portal placement.
I find a bug, and fix it by swapping the dropper.
I think this is good to go, I ship it, and I hope that people will no longer have trouble fiddling with the box, considering it's so much easier to do so with portals.
