This is the first game that i'd almost rate 5/5 on everything. Everything is made so well. My first concept for a game this jam was actually to make a Zelda-style NES game, but since I never played it and I don't have experience in making RPGs, i settled for something im more familiar with, but I'm glad someone else had the same idea and I think you executed it much better than I ever could. The sound effects sound lovely, so it's a shame that picking up healing items and killing enemies doesn't have ones.
SPOILERS AHEAD
It's also just a shame that all the build up ended up to nothing due to you running out of time. If you do make the boss fight then I'd gladly replay the game for it. Though I hope the walking speed would also be increased (or a running option would be introduced) to reduce the replay time to get to it. I ended up getting 8/8 health by the end.
