As an iPhone game developer... (Score 5, Insightful)

As an iPhone game developer myself who recently released a game (some shameless advertising: Tuzzle) at what I think is a very reasonable price: $0.99, I'm amazed by the negative comments I immediately received from people who didn't actually buy the game. Most of them complained about the fact that there are "only" 25 levels. Instead of putting 100 boring levels, I decided to design 25 challenging levels which would provide a few hours of entertainment. For less than the price of a cup of coffee, I still think that this is more than acceptable.
I have the feeling that these days, only quantity matters and people got used to have everything for free with the Internet and expect impressive graphics, hours of gameplay for free...
Is $0.99 for a few hours of fun expensive?
