Out - thought I needed tons more batteries. All that up and down stairs may call for a nap on the beach ..

I played the game twice and could escape with totally different number of batteries, the second time I even didn't have to put them into the clock

Out, but never used the flashlight.

I never got

the batteries out of the flashlight (torch), nor the batteries into the clock. Just the sprocket.
