<Let's continue!>
Anywho, I wonder what awaits us at the end of this puzzle. After all, this is only Chapter 1 of the Mr. Stick Adventure series.
Hmm...what surprise hides behind the prize of freedom? 
<More puzzles, rooms and mechanisms await you ahead! At least in nearest future. It's all I can say now.
Very honestly - I don't know what will happen at the end. Since originaly story, its plot elemnt, rooms, puzzles - everything were creating only after reading players' last commands. Nothing was created more far then one step ahead (by step I mean single pair of posts "your commands - my reaction on them").

Imagine if it was another room and locked door that looked identical to this one. 
Unfortunatelly, this is what Mr. Stick thinks so. He is sure it won't be too easy to simply get out of there after solving one puzzle. Considering things he has seen so far, even if there was just a few things - whoever put him here without his will, with unknown final purpose, won't let him go to freedom so easily.
He thinks so not only because of being here in current dark circumstances. Mr. Stick has kinda pecimistic character in his daily life.
But he won't give up. He must reak through to freedom, no matter what obstacles will be met on its way!
Ok, where did he stop?
I admit, it was tempting to press the red button. But then Mr. Stick would be stuck in that room forever if he pressed it! 
Now, press the green button. 
I too was (and still am) curious to know what that red button does. But yes, the green button is probably a safer bet for now.
Yes, the button! Mr. Stick likes green color more than red. Its color whispers him that it's safe... So he almost without any fear presses the button...
SLAM!!!
...and almost immediatelly becomes stunned by loud scary metal screeching sound behind!
He scaredly and quickly turn around to look at source of sound.

He can't see any big danger objects or beings anywhere.
