Overall, I think this game could use a lot of polish. The controls feel strange, and unresponsive at times.
I like the take on the theme! The town being too tiny for the two men definitely makes it stand out from other takes on the theme. The same gameplay could exist in multiple different environments, like samurai, indoor jousting, or with lightsabers, so the gameplay doesn't feel entirely attached to the town though.
For fun, it feels a bit too clunky and awkward. I enjoyed swinging at the enemies feet over and over and them constantly failing to dodge, but that felt more like an exploit than intended behavior. The animations taking so long, and the occasional failed dodge because you pushed the button too late (even still before the enemy attacked) feels bad. From the player perspective, if I press the button before the enemy attack lands, I feel obligated to succeed the dodge.
For innovation, it's a typical 1 vs 1 fighting game. It's not that it's bad, but it's a bit bland. I'm sure if you had more time to work on your game, you'd be able to add more to it and really give it it's own identity
I think the graphics could use a little extra work too. I like the swinging animations for the attacks, though I think the characters could be a little more than just stick figures. The background was nice though! I like the beach town setting.
The sound effects for the actions, though It could use some ambient music.
For humor, I don't think you were focusing on that category. I think it's a bit funny that you jump over the swords though. ha!
Same goes for mood. I'm not entirely attached to my character or the enemy, and the town existing as a background makes me feel disconnected from the environment. I like the drawing of the beach, and the little boats in the background make the scene nicer.
All round, it could still use some work, but it's a good start! I saw in another comment that you were considering a post jam version, and I hope you keep at it!
