In "hyped for you", remove the name of the company, and expand the game description to another row. Add tags. Remove the lightning bolt icon. What is that even? No, don't explain. Just remove it. If it isn't worth sorting by, it's not worth showing.
Describe what this website does, on the website. What it does exactly. Pretend I'm 5 years old. The title of this HN post ("Former game devs building a platform showcasing game projects") is 100% more descriptive than the explanation on the site, because you don't have an explanation on the site. It's a good start. Use that. Put it at the top. "Former game devs building a platform showcasing game projects".
"Hyped for you" makes no sense because I'm not logged-in. You can't possibly know anything about me. So it should show something else.
Remove the "hype" button from the "explore new games" section. How can I hype a game before I've clicked into it to view what it is?
Add pagination. (Unless you really only have one page of games, and pagination is implemented but not visible.)
Add a title that says "Project Goobii" on the page. Maybe above the "welcome".
Add left/right arrows to the carousel at the top, so users can scroll through instead of waiting for it to move on its own (and users love to interact with carousels!)
Clicking on a game in "hyped for you" shows the game, but doesn't change to a new URL. How can I share this page with my friends? How can I bookmark this game?
Also on the game page, the carousel of screenshots should be clickable and expand to show larger versions of the screenshots. Too-small screenshots are worse than no screenshots.
EDIT: More
Loading the page again, after going to a game page, shows that game page. I guess you're using cookies for navigation. Good guess, but the wrong way to do it.
Your logo is cool, keep that.
Have an "about" page with a contact email at least.
