Hello! I have a Twine game and I'm trying to find the right viewport dimensions for it. It's currently set to 1280 x 720, which looks great on computers, but when I view the page on my phone the game takes up the entire screen . It won't let me scroll down either.  When I make the dimensions smaller it just adds an ugly scrollbar to the game on my computer; there's no change on my phone.

What's the ideal size that looks good on both computer and phone screens?

EDIT: I should have specified that I have an iPhone 7. I don't have any other devices to test my game on, other than my iPad (which plays it fine).

Leafo, this is interesting.  Because when I first published my HTML5 games months back on itch they allowed scaling etc on my smart phone(Galaxy s7). Almost, as if viewing it on a PC.   Is this something that itch.io is enforcing or is it the Android version of Chrome or Firefox deciding for the HTML5 format via the OS on smart phones.  

I admit, I've been busy and haven't kept up with the latest changes to the HTML5 format in past 3 months.  Especially, with smaller devices...

Thanx
