I would like to create a game trailer, i did it before: https://www.youtube.com/watch?v=tDT3FqBzEw0 but it is not nice. Are there any rules that are speficly important by producing a trailer?

First of all, I'd recommend some proofreading: 'Do I have Superpower' should be either 'Do I have a Superpower' or 'Do I have Superpowers'. Other than that, I'd just generally suggest thinking what would make you want to play the game if you saw the trailer and looking at the trailers of other games for inspiration and to see what works for you and what doesn't :)

I think your trailer is actually not bad.

The only suggestion other that I have other than fixing the English mistake is to place branding later on in the trailer; Consumers don’t care about who made a game (and if they do, they already know), they only care about whether it will be fun or not. Thus, you should place gameplay before branding.

I think its quite a good trailer aswell. Some repeat shots, but i have defo seen worse.
