After seeing all the little gameplay clips on twitter over the months, it felt really good to see the project finalized and to get to play it! Glad you held onto it for after the jam, because something of this scale would have been pretty much impossible to achieve in so little time for a solo dev.
Very charming artstyle/animations and solid level design. The character interactions were a neat touch as well. Difficulty ramped up at a pretty good pace, so even when i kept losing to a certain part, i never felt too frustrated. I liked the air parry mechanic and how you could use it to do some neat shortcuts with the extra jump it gives you. The bosses were a very high point for me; it's just fun to avoid their attacks.
The only problem i ran into was a random game crash during the final boss (i played on the itch.io version), but other than there's really nothing i can complain about. Congrats!
