Love the art style!
Also the controls are pleasant to use. Though I think it would've been nice to show them for a few seconds after pressing Play for the first time. Took me a while to realize RMB was another attack move :)
When do I get to change the opponent? It seemed kind of random to me if after defeat the change opponent screen showed up or if the controls swapped to the opponent.
Would love to see this as a multiplayer game ;)
Nice job!
