The only issue I see here is skill issue
There are, however, few individuals such as yourself that struggle way more with the game than the average player.
Everything the game has to offer, is there for the player to discover, not to guide them, there was a quick introduction tutorial at the start, that explained the most crucial aspect of the game, there is another tutorial for running, what more do you need?
It was said that the camera has rewind powers that affect everything outside the room the camera is in, so if Yuna is not with mc in the room, and camera has no upgrades, all progress is reset as the time is rewound - simple as that.
I'm not sure what do you mean by "I can't record for some reason" - record what exactly? You can't start the night to have some fun with her? THAT is the recording, you don't actually record anything, what you see in the "cam" screen, is just to make it more immersive.
You don't lose stamina or money solely after rewinding - you lose money when it comes to pay the rent for the apartment which is once every 2 weeks in Friday and costs 10k (this is explained, you must have skipped the dialogue), you lose stamina when you go running and fight with the enemies, but just the running is also a way to increase the stamina capacity, to regenerate it you can sleep, cook food or drink energy drinks found during running, you lose stamina during some events and Friday party.
What's not mentioned (but almost everyone seems to catch up with it) is that the camera battery at night is actually your stamina.
This game is the amalgamation of devs whims, he wants the game to have this level of difficulty, so that you actually have to use brain while playing not direct your bloodstream to your dick - what's funnier is that there are voices to add hardcore mode as the game is too easy once you get to know it's mechanics and the number grows.
Anyway, you can always read comments and replies, join discord to look for answers/ask questions or familiarize yourself with our Wiki (there are some parts missing, cuz it's still being created, but the most part is quite ready)
Chill out and have fun playing,
Cheers!
