This is a superb entry and a hidden gem!! Great execution of your ideas :D
Loved the way you tied in the theme to your game, very unique and creative.
Music/sound design are great and fit really well with the art style/overall aesthetic, well done on that!
The game design is fantastic. I love that the upgrades matter in an impactful way in moment-to-moment gameplay. I had a lot of fun with the glass cannon upgrade hahaha. Great job on giving the player the control to spec into their own play style!
Overall a really great entry and solid work by everyone, well done! :D
