Regardless if this is the correct answer, I was wondering: Is this also related to the phenomenon that when an amoeba is enclosed at the start of a cave, it is silent, but when you free it, it starts making noise? This is what you see very often in PLCK games.Amoeba:
BD1: The slow growing timer is start immediately (even before the start signal).
BD2: The timer starts with the first possibility of growing.
But is it impossible in BD1? In other words, what happens if you do this in a BD1 cave? The same, or does it convert to diamonds immediately?
(If anyone knows a BD1 game having this, then it is easy to try of course, but I don't remember one... )
