This is a solid little entry - nice graphics, animations, enemies to kill, things to find, areas to explore. Impressive for your first jam entry!
One suggestion: In Godot, go to Project, Project Settings…, Rendering, Environment and set the Default Clear Color to Black. It took me out of the game just a little bit as I was exploring the far sides of the dungeon and the gray background would start showing.
It also felt like the music was staring and stopping at random times but unrelated to anything I was doing.
