You explain the rules on your game page, but since the game makes little sense without reading them (I had no idea what was going on in my first play through) you should really include those in the game itself.

I think you need to give better feedback on what action I have taken and what effect it will have. Your combat system takes the action of the first button I press, but with no animation showing me I have locked in a move, it can be confusing when I change my mind and press another key and it still does my first action. I would change the currently chosen action's icon's color to indicate what the player has selected. You may also want to add an animation to the health bar to draw attention to the fact that someone is losing health.

The game being turn based, I'm not sure why you included the timer. Although, I don't really get why normal 1v1 fighters have a timer, so there's that.

Once I read how to play, I did enjoy the game. The art looks pretty good, and I like that you gave your two characters unique abilities instead of just being two people in a fist fight. Thanks for joining the Jam!
