It looks sleek. I have only one real nitpick: Itch’s default page style doesn’t put some distance between the menu bar and the banner. When you’re logged in, the banner ends up touching the menu bar, while when logged out, it touches the top of the browser. Both of these don’t look good.
I avoided the issue by extending my banner image vertically, adding empty space at the top.
Also, fun fact: 9-bit digital computing isn’t that absurd. 9 bits was the standard char size on 36-bit machines, as the C specification demanded a minimum of eight bits, and 9-bit characters, along with 6-bit were common conventions at the time.
