Hi!
Pretty good work on this game, but I'd like to give you some feedback on how to make it even better :)
I have not gotten to the first dungeon yet because it's pretty difficult... I like that it is difficult, however if difficulty is the intent then you really should play around with the balance between being forgiving and fair. What I mean is that right now you're neither fair, nor forgiving as of now. A simple way to be fair with the player is to give the player a few savepoins during their adventure. If you take a look at Breath of the Wild, the enemies are awfully hard in the early stages (until you figure out how to beat them more efficently), and the game feels really unforgiving, however, to compensate for the difficulty the game saves just before every enemy encounter. I'm not saying that this games need that amount of savepoints, but a select few is really needed. Or at least do it like the original where you keep your items upon death and if you are on the overworld you spawn at the starting area, but if you die in a dungeon you spawn in the dungeon.
Also, a map would be helpful. I don't know if you get it later in the game, but maybe the map could expand as you explore, similar to strategy games like The Settlers?
I miss inventory sorting... I had to drop items to manually sort it, and that feels awkward...
Having more itemslots at the same time would be nice, because it will get a bit tedious to always open the inventory to change between bow and sword/hammer
And I would love Nintendo Switch controller support, because they fit retro-games perfectly and connect via bluetooth :D
Btw, I'm a composer so contact me if you'd like to collaborate on a soundtrack :)
