Super fun game that is really authentic and hard as nails!
The music and sound effects are top notch and controls are smooth!
The only minor negative I can really say is that I'd prefer the enemies to have some visual feedback towards the player before they take actions ex.: the balls that shoots a 4 shot volley then rush you got me every time, if they blinked or flashed before rushing you, I'd might have had a better chance at avoiding them (or as another valid possibility, I suck at the game :D)
