This is... interesting... to say the least. I have seen many bosses over the years with devastating power bullet hell wise. The hardest boss I have faced by far is stage 5 of danmaku legend II. The first one is ok (in all 3 phases). The second one... RIGHT out the gate hits you with the nastiest bullet pattern I have EVER seen. Anyway, through all the bullet hell games I have played, I never ONCE thought about being the boss. EVER. Gameplay wise plays almost like Frantic 2... except you are now the boss and the Computer is now the player.
