> don't pay attention to most of the negative things people say here

This is good advice.

> they can't stand to see someone as young as you being more productive than them.

This is not why people are being negative.

If there was no indication of OP's age, do you think the comments would have been much more positive? And if someone asked something like "how do you find time to make games?" and OP had said "I'm fourteen", do you think negative comments would have started springing up?

But it's one thing to see something cool and then realise that it was created by someone young; it's another to see something that is only getting attention because it was created by someone young. And you can't necessarily know whether that's true or not, but having "I'm fourteen" in the title makes it more likely that it's true. This isn't jealousy, it's more an attitude of "I don't care how old you are, I care about the cool things you've made; and if you think your stuff is cool, why are you talking about your age?"

Whether you agree with this attitude or not, I'm pretty sure it's a more accurate model of the negativity than your belief that people are just jealous.
