Even if I am okay with paying for a good game, I hate IAPs because they make me confused what I should purchase to have the "normal" game difficulty, as it was intended by game designers, without it being too easy or too hard.
The only thing IAPs should be used for IMHO is for additional levels, but never for items that make the gameplay easier. Difficulty should be either controlled in settings or levels should have variable goals - like simply completing the level versus completing it with three stars or something.
