Very polished game! Really enjoyable, and the art and audio feel quite good when playing! The only thing I didn't like was the fact that killed enemies still have the collider and it doesn't disappear until the end of the death animation, and because of that, for example, I can't shoot through them to prepare the bullets for the enemies that are coming behind. Don't know if it is a bug or a feature, but except of that, really good game and original approach on the theme, good job!
