Thank you, this is a lovely write-up, and Monsieur Bernard sends his compliments on the black stripe. 😄
You found a real bug, not just a missing sentence. There is a little “hold to torch ↗” note by the nozzle on the first plate, but it vanished for the rest of the night the moment the flame first touched the sugar, even on a 1/60-second click. So your very first click erased the one hint that would have told you to hold. Exactly the wrong way round.
It will be fixed with the next update after the jam: the note stays until one press has kept the flame lit for a full second, and a click that lets go too soon makes the note jump up again. Your four sessions have become a test that clicks six times and checks the note is still there. It’ll be in the next build.
Merci for sticking with it, and for “a real material simulation, not a progress bar”. That one’s going on the kitchen wall. Allez!
