Up to the Level 4 darknut room where I got hopelessly stuck, this is a hard one to manip!
It is 602 frames ahead of this WIP by jprofit22. It also has potential for more savings, as it setups up running out of bombs + bomb drop to switch to the wand for the upcoming key room to save a switch.
An important thing I've learned in TASing this game is to not be afraid of damage boosting even if you can't refill life before picking up a triforce. Boosting can net up to 16 frames, but the health refill of a half a heart is 21-22 frame. Nominally this is a 6 frame cost, but in this game you can easily gain or lose frames like that depending on RNG throughout every room. So it is worth attempting dmg boosts to see if you get more favorable RNG over the course of a dungeon.
