There's no info anywhere on this game strategy speedrun-wise so I decided to post here from my discord comments when I played it.
I used this as guide:

Some notes:
1. Item addresses are static, but instead of being fixed item wise, it's based on position. So everytime you get a new item, the amount in "item 1 amount" will change, and the previous one gets pushed to "item 2 amount".
2. 0027B614 is the main amount of rupees you have.
3. "time before shrink" is a counter that runs every single frame in the overworld. Once it reaches 0, the tower shrinks, and you become unable to access the latest region you just unlocked.
4. While you can throw 495,400 rupees immediately to access Auros Ruins, you need 5 Super Rupees to start the Uncle Rupee fight from the following:
* Hometown Prairie (Start)
* Cape Treasure (1,650 rupees)
* Deku Forest (11,650 rupees)
* Gooey Swamp (56,650 rupees)
* Mount Desma (191,650 rupees)
* Fairy Garden (313,150 rupees; to skip Auros Ruins bosses using clip)
* Auros Ruins (495,400 rupees)
5. There's 4 speedruns of this game, 1st being 3 hours 50 minutes long

6.
https://www.nicovideo.jp/watch/sm17003432 there's a single TAS of Auros Ruins boss fight, but RTA skips it by clipping out of bounds in Fairy Garden using the fairy cart.
