I kinda don't like this quest's overall presentation.

Is it fun? Yes
Is it good? Yes
Does it fit the requirement specs: Not at all. The subscreen's changed, there are like 3 entrances per level, and lock blocks (ugh). And this is only Level 1. (and kinda marching around without a key after using the boss key on a block, which I absolutely loathe, but that's not an authenticity error). I feel this has more of a "custom quest with the Z1 Overworld" type of feel and not enough in the NES authenticity area. You might want to rethink this one and fix some of these things.
