This was a lot of fun! I like the design of the character, sword, and especially the enemy robots! I like the way the wizard squishes when he takes damage (and maybe other times too - one time I lost and he squished at me to establish dominance and it was great).
I'll echo what some others have mentioned that the game was pretty hard, with the snowballs from offscreen and sticky enemies being the toughest parts for me. I struggled with the parry mechanic but eventually kind of got it :) One thing I was a bit confused by visually was the way the enemies you have to parry carry their shields to one side, so I thought I just needed to swing from the other side, like Wii Sports or Skyward Sword. I'm not sure if there'd be a different way to draw their shields, or make them resemble the practice parry target. I probably should have figured it out since it was right after that tutorial, and I was only confused for a couple tries, so not a big deal either way.
I also liked the tutorial for movement and attacking built in as you progressed through the first level. I think that's a good way to do it!
