While quite short, I think the setting had a lot of a potential to explore interesting gameplay. It had a cool theme with the graphics and music which went well together.
From a design perspective, one thing that could be improved is how enemies react when attacked - when I heard the 'clanking' noise I didn't think I was doing any damage, so maybe changing that sound and / or adding an animation or other indicator could help make this clearer.
Nice job on your first public game jam submission! :)
