thank you so much! some of that indeed are small bugs that I overlooked, I'll try to fix them soon. the typing of one key at a time is on purpose (this project is meant to be used "in real life" in combination with an analogue typewriter)
that's such a cool idea, I'll play around with it. right now each symbol is independent of its neighbors (except for the bezier curves piecing them together)
yes, it's a known issue unfortunately. I couldn't get it to bring up the keyboard (I tried even with a hidden text field) hopefully you can try it on desktop
