I regret not posting it before Canvas 2025, but hopefully it'll be useful for people playing it in 2026. All letters are 5 pixels tall, and most 3 pixels wide (some 4, a few 5). I've also included a few Cyrillic letters and the digits.
I tried to make it even smaller, but it gets really funky.
I didn’t read the post and took longer than it should have to realize that the bottom half-ish are non-Roman. (Numbers are Arabic! So half!)
I… speak Russian tho (badly, non-fluently), so I should have known..
