I got through about 30 (non concurrent), and I'm sweating. Your game tutorializes itself very well by starting slow and building momentum. I thought it would be more of a puzzle game, but some of it seems to be exactly what you said, challenging trials. Whenever I got stuck, I'm glad you had the skip option, but usually the answer was observation and patience. You definitely made restarting painless, which is a huge plus for games like this. Thanks!
