I was doing some research and found some games there, a bit cheaper than in other places. I wanted to know if it’s really trustworthy. And how does it work? Do I pay via Pix and they send the game key by email? Is the game really mine forever just like it works with Steam? How can they sell cheaper than the official stores?
Has anyone bought there before?
I don’t know this one, but there might be something on ReclameAqui. Assuming the domain you’re referring to really is hype.games and not some variation. The information I found was:

And here’s a video from 5 years ago:
Now judge for yourself.
Hype Games is known as Level UP Games.
Anyone who played Maple Story, Elsword, Grand Chase, Combat Arms… on the BR server knows it was packed and still went bankrupt lol
Problems I’ve seen are delays in keys, stock running out, or buying the wrong key, like a PS code and trying to use it on Steam.
You can solve it through support.
It’s reliable, yes.
You didn’t mention The Duel 
man, I spent endless hours on that game when I was about 15. I spent a lot of time trying to learn that double butterfly. I didn’t even know Level Up had gone bankrupt. That’s crazy.
