Neat little Metroidvania you did really well considering the time the art is really cute and I loved the animations for each of the different attacks I also liked the cutscene at the start which helps with the story.
Though it did suffer from punishing platforming and difficult enemies from the first level onwards, a checkpoint system would probably help this be less harsh(if the jump was variable heights depending on how long you pressed down the jump button could greatly help the platforming aspect of your game-similar to hollow knights jump). The variety of enemies you managed to add was also a great thing to see. Well done, this was a very cool little game!
