Well, let's think. I like the idea for the first boss, but I had a different way of beating it. It could be one-headed, giant, and spinning slowly in the center of the room. It's constantly spitting rocks at you. To defeat it, you have to bop Link into its snout at then it pops up with a window showing Link inside the thing. Then, just bounce around like crazy, doing damage until you kill it. It'll spit you out when you don't kill it, byt the way.
@Hikij: Well, it's not traditional Zelda at all. It's Zelda Pinball. And, everytime you have to climb a tree, you won't go into a pinball level. Only for really big cliffs and vines. Like this: You're at the base of a mountain. You have 2 options: Do a pinball level and climb to the top quickly, or go through the level traditionally, and take longer.
