at vs. on all levels

[Arteberlina]

Would you rather say: on all levels or at all levels

the original sentence (about an artwork) being:

On/At all levels it (the artwork) says: What you see is not what you get.

Thank anybody for advice.

Not a teacher.

You could rephrase it...

The artwork screams: What you see is not what you get.

korotama, your answer does not address the question. A rephrasing was not asked for.

Arteberlina, 'on all levels' sounds better to me, but I can't say 'at all levels' is wrong.
