Thanks for the feedback! We suddenly didn't have enough time to add an attack/button animations or tutorial, but developing this was a good experience.
Oops, it seems the problem was in my browser. When I ran the WebGL version, there was no sound at all. Although everything was fine in the windows version.
I agree that the effects are pretty funny. Unfortunately, I can't say the same about the rest of the game. But we got an interesting experience and had a good time. This is probably the main goal of game jams. Thanks for the feedback!
