Really nice artwork in this game! The characters are cute, and I like the drawn background art. It all comes together for a great aesthetic!
The run and gun gameplay is fun, and there's a good variety of enemies and bosses! If you're planning on expanding this game, I'd like to see a little more variety in the attack patterns and abilities. Currently the best strategy I found was to just keep pressing fire, and heal when my health gets to the danger zone. More emphasis on dodging or other strategies could help the gameplay stay fresh. Dodging was important against the bosses, and those were my favorite parts of the battle sections.
Great work!
