I decided to rate the first game and last game submitted to the jam. You were the first submission. Congrats!
For being the first, this is a really well put together short experience. I think the art and style is adorable, and even though it's such limited pixel size, everything was easy to read and identify as far as gameplay elements. Kudos for that! The swapping mechanic was interesting, but there was rarely any reason not to just go hogwild swinging the sword around.
After a few rooms I realized I didn't actually take damage. It's a shame, because I would have enjoyed the combat a lot more if I needed to make purposeful decisions, but without taking damage I just tanked through. Still a fun experience, though. Great work!
