I feel like I'd love this more if the combat felt less random and slow. Except the character that can double jump the characters are very slow and can't do much to dodge attacks. It feels very frame perfect and for some attacks you can't do anything if the boss cast the attack in a certain pattern (like the floating rocks that sometimes literally block me because I need to collide with the boss to dodge, which is just less worse than taking the 10 damage from the rocks).
Outside of this it's cool, you did an impressive job for animations and visuals, and the bosses are quite unique. I really appreciate the tutorial, simple and effective. Also the character that attacks with ducks is too fun to lay, there should literally be a whole game based around this!
