I'd like to jump in too... it was only mentioned briefly, but what about jumping? Is the jumping pretty good?

My jump will land me on the next block above me if there is one... technically, I could ascend a 10 story bulding from the inside, 1 floor at a time, just by jumping... but then, this was a simple 'lets see what it does' code.. so how is the jumping in the Zelda code?
