Really liked it and having the little cpu units(?) as extra collectables was also a really nice touch. I thought it was a bit difficult to tell exactly when the moving walls would reflect my projectiles and also the movement felt just a bit stiff. I really liked the level design though and thought the main mechanic was really nice. Also consider somehow locking the firing of the projectile to the beat of the music! (Though I know that's quite difficult hehe) That would make it much more intuitive I think. Nice job!
