First launch feedback

I did my first-ever launch today and got to admit I was super nervous ahead. I think the longer it remained un-launched, the longer I could hold on to an invisible reward. But I am actually really glad I took the leap. How do folks on here cope with the nerves? I usually like to go for a run or a bike ride. I am also curious if people would like to see authentication added to the Perfect Score product. It would add an extra step for the user before they can play but it could also add so much scope for tailored experiences. What do you think?
