It looks like you put a ton of work into this! It has a very classic NES feel. The overworld screen looks amazing and suggests a massive amount of content -- especially for a jam game. As a new player to the game, I felt like there was too much text tightly packed to read up front... would be nicer to roll out the lore in smaller chunks after I'm already invested in the game. Even like the first town seemed like there were too many buildings; and the first dungeon was too large and too difficult (maybe make those round shell things easier to kill... like one hit instead of three) -- especially since the player dies so easily. The very low jump height was tough to get accustomed to after playing other really jumpy games. Also, the two grey columns on the sides look cool, but take away from your playable real estate.
