I'm glad you enjoyed it despite all its flaws! Congrats on getting the job, too.
Yoga (should) resolve the achey status, but that sounds like it may have bugged on you. Going on a walk was also designed to resolve that status, but we weren't able to get that working properly for some reason. I'm not sure why you got locked out of meditation-- there was nothing required to unlock that, unless you were totally out of energy. Meditation, sleep, eating a meal (as opposed to snacks), and playing video games were the main ways to combat burnout. There was also a planned 'phone a friend' dialogue opportunity that would take a big chunk out of burnout once every few days that we wrote, but we ran out of time to implement it.
A tutorial/more hints to the player about the costs and benefits of various activities is high on our list of things to tackle in the future (and clearly a lot more QA/bugfixing).
