Type. Everything about good typography is optimising for legibility. First off, you absolutely nailed the line length. I did increase the line-height to 150%, and swapped roboto for inter. I think Inter UI is a bit easier to read at small sizes, I find roboto comes out kinda excessively bolded on most screens.

Grid / padding. I increased the padding around the card quite a bit, from like 10px to 24px. A good way to find the correct padding is putting in way too much, then pulling it down until it's starting to feel cramped, tip from refactoring ui actually. Everything is in 8px units where possible. Notice the "Welcome to" and "Hello" text are both vertically aligned.

Sizing / visual prominence. Visual prominence is just about telling people where to look first, when you first open up the page, where is the eye drawn. Considering the size of the 'Welcome to Gnod' text, I assume that's what you're trying to highlight. I've reduced the size to just 18px - only 2px bigger than the 16px body font. But, cause it's got it's own padded background colour, it's still right where the eye goes. There's lots of ways to draw attention without size, and you don't need to use more than needed. Same with the dots, I don't really get what they're for honestly, but I made them a bit smaller.

Icons, swapped them out for font-awesome icons, felt a bit more premium idk.

Colour, I changed the pure black to off-black, slightly blue. It might seem like designers just hate contrast, and that might be true. But, there's lots of arguments for using 'rich' blacks, but I won't get into it haha. My subjective choice.

Anyway, that's my 10 cents, ignore as needed haha.

Also, the top feels like a logo, navbar, and a hero all in one. I would work on it more as a logo and lose the “Welcome to” since the next sentence also functions as a greeting.

The green dot is an interesting touch, but presently looks like a status indicator/green light, that, on a black background, attracts the eye more than the content and the sign-up button.

Suggestion - I tend to forget these kind of things once a couple of weeks have passed (or at least, forget the name and can never find it again). It's good to have something prominent that I can subscribe to that reminds me what it is you do - a mailing list, Twitter/RSS feed/etc.

I know you have your Patreon, but being honest, I'm unlikely to subscribe straight away the first time I play with something for 30 seconds or so. I need that mental bookmark so I can come back to something a few weeks later. After coming back three or four times, I'm much more open to subscribing.
