Apologies for coming off as rude. I was simply assuming by how there are screenshots showing the game at a much larger scale, though I can guess those are either illustrations, are from an earlier version, or were taken on a device with a lower DPI.
I was actually fiddling with some of the CSS to make it scale with the window's size when I posted that. I ran into something of a brick wall and kind of wasted an entire day on it, but now I've actually got it! I made the game scale (mostly...) nicely with higher window sizes.
If you want, I can supply what I changed. Though it definitely isn't perfect.
