Thanks for the feedback! I think the text speed might be an issue with my implementation: it adds a single character on each animation frame with a WPM speed limit, but this would cause problems if a device isn't able to animate very quickly. A better approach would probably be to use the wall clock time to figure out how many characters to add on each animation frame.

As for SVG, I've used that in other projects but since I was working with pixelated drawings instead of vectors, I chose canvas instead. The downside is having to do a lot more of the work on animations yourself (but this ended up being an upside for me since it was a lot of fun :) )
