The video looks fantastic! Glad to see you've worked out your Stalfos issues from earlier this month. The disappearing bridge looks great too.
I hadn't seen any blocks breaking until later in the video, and I'm curious as to whether or not those had been solidly-coded as well. Can enemies like the slimes be destroyed from underneath, like Goombas in the original game?
Almost all the different blocks in this game are coded uniquely and as such they work a little bit different from each other.
These "Hard Blocks" as I call them doesn't kill enemies when destroyed. The reason for this is that I try to make every object as close as I can to it's original counterpart.
These "Hard Blocks" doesn't kill enemies when destroyed in Zelda II.
However, slimes and other enemies can still be killed from underneath if they are standing on SMB bricks!
