Never played Adventure but wow this was a very fun 15 minutes. I really felt the sense of discovery in this one!
I read the comments below that mention the swapping priority over throwing. It did confuse me at first during an enemy room cleaning, but I did find a use for it. Mashing Z while moving, I could "carry" 2 items at a time. I'm sure that wasn't intended but it did save me from some round trips.
