I really liked the animations (esspecially the sword swinging and the enemies dying). It's a fun game!
Possible fixes: make the text a little bigger, don't inculde the first cutscene every time you respawn in the first level, introduce more game mechanics in the other levels (you get all the abilities in the first level, and afterwards it feels just like a regular platformer). But most importantly make the boss level easier, it was too hard for me.
