Neat little game. I like the shield mechanic.

I'll need to try playing this with someone else. It looks like you tried to make it balanced (ducking/shields prevent a player from winning just by spamming high-attack, etc.) However, I think that since there's no limit on attacking and no way to avoid low attacks except for blocking, that a player only doing low-attacks the entire time seems to be the best strategy.

I like this game it´s funny to play it together and the balancing works now! The short cooldown after attacking twice is a gamechanger! You graphicdesign is simple but awesome!
