Copying is a form of praise (some say).
And I will be honest for a change; I am just a thief.
And as such:
- I am lazy (yellow)
- I (mis)interpret the rules whenever convenient. (red)
- Things got more complicated (for a thief, things are only easy on moonless nights)
That should not prevent you from decoding my message, especially if you know
[ the answer ]
Hint- If the direct approach is preferred
The title is in plural, it does not (only) refer to reflections of the thief, it refers to a multitude of reflections.
Hint- Following the story
"I (mis)interpret the rules" So the rules are made somewhere else. Probably rules about (letter) grids and/or 'self reflections'. were used by someone (before this puzzle was created). One could try to find those rules.
If you stand before a mirror, you are real, the mirror image is not + you see the mirror image, not yourself. So: find the original, remove the reflection. This may not be easy if there are multiple mirrors.
Start with self-reflections of the white squares, they have nothing special mentioned.
Note: I am not happy with my grid-deduction tag; it does not fit well, also 'letter' is not a very good fit, maybe enigmatic-puzzle (added by oAlt, thx!) should be the only tag. (Suggestions, probably after the puzzle is solved, are welcome.)
