This is a tiny thing that just kind of bothers me and i'm not sure if it's intentional or not, but when you use a hammer on the very last durability it has, it breaks the block you're hammering but does not convert it. I.E, hammering sand into dust on the last hit of the hammer breaks the hammer and drops sand, rather than dust. I figure it's something pretty simple to fix, just thought I'd point it out.
