improved upon my time
IGT
RT
main things to improve upon would be overworld routing, i think it might be possible to get from each sequential dungeon (forest > father > son > holy spirit for my current route) without triggering any overworld battles. could also try (holy spirit > father > son) or (father > holy spirit > son) but idk if the shield bypass is worth getting earlier compared to getting HT from/nullifying red nails
smaller improvements would be menuing and maybe timing attacks so you start blocking when theres lots of (white) nails to get HT faster, but id need to see if theres any case where that can save a turn and thus more time compared to just attacking instantly
also itd be nice if there was a way to skip the credits without closing the game
