I loved the concept of the shadow puppets fighting in this game! I also liked the visuals of your game and the sounds that you made!
Some feedback I would give is that sometimes attacking doesn’t feel like it registers an attack because maybe the range is short. Maybe it is because the opponent blocks and if so, I think it would make the game better to give the player more feedback when they do so it doesn’t feel unfair (even when it is fair after all).
In any case, very good job on the game.
