I've beaten the original LoZ several times before this, but this time I played through it entirely while vaping weed and kept notes on my progress. I still have a very good memory of where most of the dungeons are in the 1st quest, and that combined with the cryptic in-game hints is enough that I can play through to the end without a using guide.
The game begins at the 8th square from the right, and the 8th square from the top. 8-8
I know right away to go north to the Eyeglass Lake, where the first dungeon is located in a tree on the right eyeglass island.
Level 1 - Eagle Dungeon
Eastmost peninsula is the secret
Got map, compass, boomerang, bow, defeated Aquamentus and got a heart and a triforce piece.
From there, I backtracked a bit to the shop near the beginning area, and bought the blue candle... then I used that to find a few "secrets to everybody", plus a few angry people that made me pay to repair their door... Then I went to burn a couple trees near the Eyeglass Lake to buy the discounted magical shield and meat, and get the 2nd heart container...
Then I went exploring north of dungeon 1, east across the desert, farmed a few more rupees, found the 3rd heart container in a cave, then explored a bit of the mountain... Found a staircase under an armos statue, with an old man who says:
Secret is in the tree at the dead-end.
Explored a bit more, and found the white sword at the top of the waterfall.
Master using it and you can have this.
Went back to the east, to the northeast most section of the map... found a dead end with a rupee gambling game inside a tree... this must be what that guy from before was talking about... yep, as I was bombing the north wall, I found a hidden fake wall that lead to another area, with a 100 rupee "secret to everybody".
Also found a high up cave and got the letter that lets you buy
potions from the old woman... the first "trading quest" sequence of the Zelda series...
