The lack of polish regarding the text and the thing with the C was just bad time management on my side. :) The interaction button not working consistently was one of those last minute ‘fixes’ that broke other things (this is one of them).
The running is certainly preference though. I like it this way and got positive feedback on it as well. Certainly takes a bit more attention and care. If the alternative would be holding the button, I’d keep it out and just make a higher default speed anyways.
