Ok so I've played for several hours now and its a great game so far but I have a list here of issues/suggestions as I promised on Twitter:
-torches required in every dungeon is not very beginner friendly and a bit frustrating for even zelda vets. I suggest making oil torches on walls of rooms that dont go out once lit. In early dungeons and many later dungeons they should already be lit. But they start being not lit or not present in later dungeons rooms.
-going to stair well restores life without seemingly changing damaged health of enemies. Makes end bosses alot easier which is ok if its intentional but there should probably be a penalty of some kind like partially or fully restored health of the room enemies.
-I thought I remember a bow and arrow in the game before but haven't seen it so far. Would be very helpful against fire breathing bats/little dragons when they go over pits.
-more or some item drops from enemies or at least some reason to kill non-boss enemies. Since the orb of ascension is the way to level up and no experience points appear to be in the game, non-boss enemies seem best avoided besides annoyance factor.
-it would be nice to be able to visit every map land section to look for secrets (hidden caves reveled by bombs, chests under bushes, etc) and use the overworld as more of a quick travel. Over the water might be an exception unless you want to make a fishing or octopus fight options from the ship.
-what is the point of the clearings? I have visited many of them and it just one map square with no enemies or secrets that I can find.
-Villagers so far only say "nice to meet you". They should probably have a more diverse vocabulary for immersion purposes even if their village quests haven't been implemented.
-give certain enemies or items and item switching abilities/different attack types at higher levels.
-could use more environment, building, enemy, and boss diversity but I know that will come in time so I'm not really worried about that ;)
Thats all I can think of at the moment. So far its alot of fun and the dungeons are pretty decent as far as secrets and progression even if they are somewhat linear at first. Great effort and keep it up! :D
