Does everything _really_ need to be compatible with a phone screen? Use a computer to view the website.

No, and it's fine if you just want to make a desktop site, but if you're designing a game or UI then why not add some nice touches to make it look as good as possible on any size screen? Everything I've designed in the past 15 years has tried to cater to both with whatever adjustments can be made to make it take advantage of more screen real estate if it's available, or rearrange to a compressed visual format on a phone. It's not hard to do, it's just a series of design decisions to make whatever you're doing better across platforms.

I'd even argue that in this case, on desktop, you could have a whole side panel with play by plays, while on mobile you could make the small UI elements larger, without losing any of the charm of either one.

Did you add Ribbie to your home screen? That mobile version makes better use of the full phone screen.

Yes, and it helps some. Still wish there was a mode for people who need to squint to see the score.

Hear you! Will try another pass for mobile legibility.

Really like it though! Lotta fun. From a guy who codes games and usually has baseball on some screen next to me while I'm working ;)
