This game is sooo good.
I partiularly loved the IVE GOT IT moment after failing many times. It was always a surprise that every room had a different mechanic (For example in Room 18 you were supposed to turn OFF the buttons not on)
Every time I discovered a new room rule, I enjoyed the IVE FINALLY FINALLY GOT IT AT LAST!!!!! moment
