I drink a lot of coffee and don’t notice a strong effect, I meant some kind of (spoiler) monsters like if the stamina is low? or the same monster that takes you into a nightmare if you haven't slept for too long.
By the way, I knew about the radio that I could give it to her, but I forgot xd. I didn’t know the rest, thanks! By the way, I noticed one consequence from coffee - camera shaking.
