Skill Issue. Now, I'm a bit sided by my own game but I think your game levels are maybe too big, if they where smaller like an arena I think would be nicer. Also, I know the game is hard, but it's not like the first mistake you do is your last, you have a lifebar afterall :p
The Parry system and visuals are really great, you guys made a very cool game and I loved the easter egg in the quit button even though in the browser version when it actually tries to close the game the game just freeze.
Congrats to you guys and keep doing games!
