Ah, yes. Standard Edition does not have the fake suit, and the lights indeed do not turn off, but it is passable. This is intended.
Though, the Standard Edition was discontinued, the Standard Edition and the Special Edition in Changed3D have been merged in the latest versions and it is only one, extended version.
Otherwise, look up for a gameplay video on YouTube and you will see how to go through it.
If you feel there is indeed an error and it cannot be completed, please provide a video instead.
I'll be on the look out!
Edit: It seems the lights do indeed turn off in the original, Standard Edition. Oops! my bad. Though that's not something in particular I will be changing now.
