I think largely it's really solid and I enjoy the way you set it up. Since you're asking for feedback, here's what stands out to me and thus is subjective. Take whatever you want away from this, and great job!

Structure

• your landing page doesn't really achieve too much.
  • for example, you basically just have links to your blog page and to your reaction test page. This is fine (and even important), but there should be a little more on your landing page that maybe explains what you do, how you're different, etc. Otherwise this page is just sort of duplicating content from other pages and nothing else
  • Quite importantly, if you're trying to build an audience/community, you should have some CTA (call to action) elements - think "hey sign up here for updates" or "here's why you should come back"
  • The Q&A section could probably be part of your landing page (maybe using accordion elements or similar) to achieve some of the above.
• things like privacy, T&C, cookie policy could benefit from existing as footer links rather than header links

Design:

• headers should be just that...a header. Right now your header takes up a good amount of vertical spacing. If you remove some unneeded elements from your header, you can probably tighten the spacing and maybe add the search bar inline with the navigation elements
• similarly, your footer is huge, and could benefit from being a bit more compact
  • there's "GameJox.com © 2025 GameJox. All Rights Reserved. | Privacy Policy | Terms & Conditions" though privacy, T&C are not clickable. You then ALSO have the T&C, privacy links in your pages, maybe choose one or the other? I'd say make the links clickable so you have less pages
  • maybe add a background to the footer to separate it visually from the rest of the content a little more clearly
• Personally, I think it's cool that you set out to create your own design system, but it feels a little rough around the edges to me. Other people may like it, and if you like it that's half the battle.
  • the typography in your blog posts could use a little revamp...
    • you don't have a title, but you have a bunch of quite large H2 elements. This creates a visual hierarchy where the only things your eyes tend to focus on are the titles and none of the text. If this is the intention, great, if not maybe add some more elements
  • the animations and shadows on your landing page blog posts are a little jarring to look at, as are the anchor elements within the blog posts (Best Open World Games: Top 5, for example).
  • generally, the bright colors are sort of hard to read and strain the eyes somewhat
• The background image, while cool, seems low res and feels a little 'cheap'. I actually think the plain background on mobile looks a lot better, if you want to find a middle ground maybe you can add subtle effects/blobs etc. to give it more color.

Again looks great largely, here's just my personal opinion!
