Super cool use of the theme, easy 5 stars on that. I like how much it restricts the player, making the controls and gameplay much more intuitive. One thing i would change is to probably make the projectiles of the first boss smaller since atm its really hard for the play to dodge some of the attacks (especially the ones that go all the way through the center of the record). But i really like the visuals and again the overall gameplay. Well done!
