Thanks, this is really useful feedback, and you're right on both points.
Running straight to the fridge works too well on night 1. I'm going to make Grandpa react much faster to running, so sprinting becomes a gamble instead of a shortcut.
The black screen after you get into bed is an audio outro (try it with headphones and listen to what's outside your door), but it shouldn't count toward your time. I'll fix the timer in the next update.
