Just played through the game for the first time in >20 years, with this 2.0 hack (and no guide this time). Allow me to give some feedback (apologies for not reading all 37 pages.)
The automap made exploring actually fun, it pretty much eliminated the feeling of having no idea where I was or how to get to a particular screen. The wall/bush hints were invaluable, I often overlooked shriveled bushes so good job making that subtle.
In the item menu it bugged me a bit I couldn't use up/down to move between the rows of items. The Select functionality is nice at first, but once you have >4 items or so I found it more tedious than the menu. If it only switched between certain common utility items, like Bombs, Candle, and Boomerang, it'd be more useful; it could at the least skip past the Letter/Bait/Flute. While on the topic, I'm unsure why the letter is retained after it's used. It and the bait could easily be passive items automatically used when needed.
I concur with prior suggestions of hastened dungeon screen transitions, and looking into diagonal movement. I could see the latter causing issues with balance, though.
Given the visibility of most secrets, it kind of sticks out that others aren't signposted at all, particularly pushable blocks in dungeons, and room drops when they are cleared.
An audio cue (like in LttP) or something visual to indicate these secrets would make it more even. A few hints were overly obtuse, as well.
I find it mildly amusing that people hiding under a bush chastise you for destroying the door to their house; the next time you go to an equivalent cave the door is still broken and the occupant is gone. Maybe change it to e.g. "You ruined my hiding spot. Pay up, since I'll have to move now."
I didn't realize the Magic Shield was an upgrade over the starting shield, since they looked so similar to me. Maybe make it look more distinct?
I suggest an optional rebalance patch, since the combat sticks out as being overly difficult.
I didn't try the hearts patch, but think it only affected save games? If continuing restored all your hearts too, that'd be nice. I'm wondering why there's a Retry option, since you lose all progress since your last save, unless it doesn't increment the death counter; maybe rename it to 'Revert to Last Save' to make it clearer what it does. Also 'Elimination Mode' could be renamed to 'Delete Save' so it doesn't sound like a game mode.
I, for one, didn't think diagonal sword attacks made combat too easy, although it did help a bit.
