I have to agree with arismartie13; you need to be a bit more forgiving on plurals and forms of the word. Paramedic should work as well as Paramedics. Paranoid should work as well as Paranoia.
Paradise almost always refers to a place, maybe an experience, but not a state. I have never seen 'parameter' being used as a 'guideline' and neither OED or MW even suggests such a meaning. Also the only regular usage of the meaning 'limit' is in the expression 'within the parameters'. I would use the primary meaning to make a hint, for example (this is from OED) "A numerical or other measurable factor forming one of a set that defines a system or sets the conditions of its operation." Which is somewhat abstract, but there can at least be no doubt that the word 'parameter' is meant.
Otherwise, a fantastic theme and great words.
