Game needs a casual unranked mode

Getting a little check box added to disable or enable ranking would be awesome for several reasons ... 1) I'm always paranoid to try new things cause afterwards it take up to an hour to recover my lost ranking progress from a single bad run

2) I'm basically ignoring most of the daily quests for the same reason, for me attempting to craft something ridiculous for a daily mission, then failing and needing to spend several runs to get back to my previous rank isn't worth the rewards for the risk

3) I've got some nephews that like to play games on my phone and basically even though they'd love to, I'm not letting them play this cause they'd tank my rank so drastically
