Considering the "completeness" of many of the other entries I've played, I think you managed to get quite a bit of content in for a Jam level game.
The theme was "game design". To me, this hit all the elements. Good background music, nice sprites, the attack sound on the weapon and the sprite arcs made it feel like a powerful attack. I could see how if this were extended into a full flegged game, it would be fun to play and it managed to draw me in just with the existing content.
