Always glad to get another continuation of my favourite penguin story!
Like your other submissions in the past, this is incredibly well polished for a jam game! The music and graphics fit the feel of the game brilliantly.
I'll agree that the AI might be a little bit too difficult - it took me over 10 attempts to beat one of the fights, and I'm not sure how exactly my opponent was managing to hit me so often. Eventually I figured out that timing my dash to hit them while they were jumping worked pretty well!
Definitely on the verge of the "platformer" theme, but since previous submissions of yours have happened to have been platformers, I think that's fair enough!
