Doing a multiplayer game during a game jam is always super impressive. All the assets look really good and the music is very nice and fits the game well with how upbeat it is. I am not quite sure how the battle mechanics work, since both players seem to lose hp in similar amounts on contact and we could not verify if attacking does any additional damage. But I assume the most difficult part was getting online to work and adjusting the gameplay will be easier.
Great work!
