Up until finishing I couldn't get used to the fact that turning into the bomb was a hold, not a toggle. Because once you get lit, you no longer have to hold it, nor when you are in a tunnel - so for me it was very instinctive that "turning between boy and bomb is an action that gets disabled under certain circumstances", rather than "being a bomb is a tied to rolling". Something I would think about in a future when deciding on such controls.
