This is a cool Zelda-style game! I liked the graphics, and the music was excellent. Gave it all a nice retro feel! I wish there were in-game instructions or tutorial, but for a game jam that's can be a lot to add.
I mainly used the ranged attacker in combat. I found the melee character would get killed trying to get close enough to hit. The puzzles were fun, though I did eventually get stuck. The shop initially confused me, but I figured it out. (Max of 3 potions)
Anyway, for a first game, this is amazing work! Keep it up! :)
