>what can be improved
delete all those fucking shrines and bring back stuff like natural caves, mines, sewers, fortresses etc, generally more interesting interiors with challenges rather than a magical puzzle room. bigger dungeons, the shrines were all 15 minutes long with no challenging enemies whatsoever. dungeons should be themed and placed in good locations, like those three spring should be entrances to dungeons and not just another shrine unlock. More story that isn't just stuff that already happened a 100 years ago.
It's a 9/10 game for me, but at the same time it's also a painful reminder of what could have been.
