There were a ton of bugs in Zelda II.
The 0 sword, which killed everything with 1 hit.
Shadow Link and Wizzrobe cheap kills (sit in corner for near flawless victory)
Shadow Link dieing when Link turns into a fairy
Overflowing Magic when using spell to get the Master Key
And those are just the few I've seen personally and can remember right now. The Legend of Zelda was great too, but was even easier and missed out on the great side-scrolling link action. I think Zelda II is the only Zelda I haven't beaten 10-15 times, but only because my original copy would always have some bug before I could finish the game.
