Any tips for a new player? I tried out 6 on Normal and got around to the middle of stage 5 before my last continue was spent. I didn't use bombs because I forgot about them and I didn't realize I could slow down until stage 4 so maybe that'll help next time, I really have no idea what the fuck is even going on when I play though, I'll be dodging shit and suddenly all the bullets will disappear. I understand that getting more of the power things makes your shots stronger, and score probably does something related to score, but what does graze do?
