FOR THE FIRST TIME I FINISHED ALTTP I DIED LIKE 85/90 TIMES IM SAD ABOUT THAT
I couldn't really say for certain what my death counts have been in any Zelda games, since I have been known to both reboot the system after a death (to redo the part I died in without increasing my death count) and frequently make new save files (thereby deleting older ones). The situation is complicated more by the fact that I made extensive use of guides for my first three Zeldas: Link's Awakening DX, Ocarina of Time, and Majora's Mask. I've memorized almost everything about them due to the guides. However, since those three games, I've only used outside assistance when I'm hopelessly stumped, which happens, but not often.
What I can say is that after having played LA and the Oracles prior to ALttP (GBA), I found the latter incredibly, frustratingly difficult, and I did die a handful of times (my guess would be quite a bit less than 20 at maximum, but my aforementioned habits don't make even guessing easy). It took years before I came to like it, and in fact, I'm only now at the point where I can greatly appreciate it. Part of my appreciation probably has something to do with the fact that Zeldas first released after the Oracles have been predominantly way too easy, mostly in terms of combat, which is one of my favorite gameplay elements, and ALttP provides difficulty, if nothing else.
Anyway, with the possible exception of ALttP, I don't think my death rate has ever reached the double digits in any Zelda game. I most likely had 2 or fewer at maximum for Wind Waker and Twilight Princess, and even that number seems high for those two games.
