go ahead and drop it imo. game is much closer to bad than good so youre not missing much
if you want to finish it then just do the dungeons and the bare minimum shrines. not sure how long itll take though. and dungeons are actually one of the better parts of the game!
(note dungeons are still awful)
congrats to azuarc for victorying GotD guru
