I disagree with the parent's comment. It is useful to know your age. In the real world, I would not usually interact with a 14-year-old in the same way that I would interact with, for example, a 20-year-old. I think the context you provide helps others to tailor their feedback.
That being said: nice job! Why do you like creating games?
The OP could have included their age in a comment on the post.
By including their age in the post title they have, inadvertently or not, 'gamed' the system.
If this is right or wrong isn't really the question, but neither the title nor the top comments have told me anything about the game in question, except that it was by someone claiming to be 14.
To that end, titles like this I believe add little to the community. I would much rather see some information about what exactly is being shown, beyond the age of the author.
Aside from that, well done to the OP for finishing something and getting it published. That is something many never manage to do.
