Dang, I remember playing this during the golden days of NG. I remember this game being really hard, dying multiple times on the orange stage and from the boss slamming into me. Now though, maybe because I played Touhou and got more skilled at bullet hells this game feels a lot easier lol.
The game's still ridiculously fun, the difficulty is just right, and for an eight-year old flash game the art and graphics are still really great. 10/10.
