Also, there were a couple of things I did mostly by accident when playing through the game:
- I was able to clip out of bounds fairly easily in the first shrine, with no apparent way to get back in bounds, which required me to save and quit, because it was otherwise a softlock
- I discovered a way to make it such that enemies pass right through you as if you weren't even there, and can only damage you with projectiles. This status persisted through a save and quit, and the only way I could get rid of it was by starting a new game
(I should note that I was playing on my SNES running on SGB2 using my FXPak Pro)
