Yes, but only the actual original works, reprints are about worthless on a one by one basis. Of course as mass-production it is alot of money there.
Anyway, after 10 years most artist/writers makes little money from their works because they almost always have to sell the copyright to a publisher/record company to get them to produce and promote it
Not knowing the details on cotton the answer is maybe not.
For example your hair does not contain any DNA if it is cut off without the hair sack. Hair does not consist off cells but of a substance prodused by hair sack cells. Of course the hair can easyly be "contaminated" with dna from somewhere else on your body.
Skin on the other hand contains DNA as your topmost layer of skin is actually dead skin-cells.
So it is possible the fibers of cotton used for cotton produkts does not consist off plant cells but off a substance prodused by the cells
So you're telling me that almost every single user would reach several points in your puzzles where, for a whole 30 seconds they have no bloody clue what to do, and essentially have to surrender and use that button? And you think they should enjoy the frustration instead?
IMHO, if the game has a timer and you lose when it runs out then 30 seconds is long time to be stuck. But if it is a game with specific puzzles where when you have solved it once you know the solution and no timer, then spending 30 seconds thinking should be minimum for solving a level.
Old programmers never die, they just hit account block limit.
