You were either being a troll or you are a hypocrite. Have you actually seen this app? It's impressive regardless of age. It's gameplay and graphics are comparable, if not better, to fruit ninja. Being 14 is just a plus, it doesn't make the app any better or worse. If anything, it's inspiring (as I said elsewhere in the comments) for people of all ages to make and ship.
Quite frankly, it sounds like you are bitter because someone around the same age of you is receiving recognition and praise for their work.
>>But there is no logical basis for this. 14-year-olds face similar constraints as 18-year-olds, who probably face a similarly-difficult learning curve as 30-year-olds.
I disagree. People 18+, in college, adults, usually have either more experience (whether than be programming or learning how to learn) or perhaps some type of formal computer science background.
>> If it is good and the price seems fair, I will buy it.
If you actually clicked the link or tried the game, you would notice that it's free.
If you really believed in what you are writing, you would have no problem commenting constructive criticism about the app itself rather than ranting about posting an age in the title.
For the record, I'm 16 and I'm not making a big deal about the age in the post or being irked that someone younger than me is receive praise for his work. I think the game that NShen made is awesome.
