I've been playing with this and all was well.

Until.

I decided to use another verb. I get that x room or object is impossible in the dark. But what about smell air? It responds with "I can't see that (air)".

It was only for polish. But I can envisage a time now where flags might be better.

Ignore, I worked this out. Set brightness of object on entering room as weak and it retains its descriptions.

You're quite efficient, both asking and answering the questions.

Otherwise known as speaking before engaging brain.
