The elevator-style music of the first stage was a bit strange in comparison to the title and intro rocky sounds, but otherwise the music was top notch and the DJ screen that allowed for all of them to be heard was a very welcome addition!
At some points it felt like there were shots coming at the player from nowhere. Especially in stage 2 where the enemies had this spread out shots that lookd definitely different from the frist stage ones.
When scrolling I could see the seams between the tiles...
