All I see is an angsty teen not being able to figure out how to play the game.
Yes it has bugs (v0.4 early build means it's not a final product yet in case you didn't figure it out yourself), I'm afraid you'll have to deal with how things are for now - one person has a lot of work to do when it comes to art, story, coding, bug fixing, etc. and trust me, dev does everything he can to satisfy both parties, yet his hands can do only so much at a given time.
Some bugs were fixed in recently published paid build 0.4.3.1, either subscribe to access it or wait for it to become public (not sure when, most likely around new year)
I don't have enough info to explain and help you with your struggles, but when it comes to stamina, simply cook, skip nights and/or drink energy drinks obtained from vending machine during runs - you don't have to go to her every night.
Have a nice day,
Cheers
