I did the Deku section first, that dungeon was frustrating with the multiple entrances. Even with a map, I was getting lost/confused. I also had to go back to smaller rifts so I had enough energy to summon the thunder Wizzro for the boss. I tried with the little electric slimes, but that proved impossible.
The snow temple was fun. I was playing around and found a cheap shortcut way up the mountain. Someone else probably figured this out, but just in case: As soon as you're able to summon 2 platbooms, you can do this. Summon 1 platboom, and when it's the highest it can go, summon the 2nd platboom slightly on top of the 1st. Rinse and repeat. The next platbooms will treat the higher point as the start, but also have to go all the way to the ground before they go up again. It's a bit tedious, but def doable. After I reached Warp points, I ended up backtracking down the mountain for echoes/treasure.
Just beat Bomb Link in the Goron area. Way easier than I thought, I just sicced a Snow Wizzro and a mob bird on him, and watched from afar. Didn't even take any damage.
