You two are doing fine. What do you think of the game?
As a tip, bullet cancelling is key. Especially on bosses. The MEFA2 + concept reactor will take you very far. The faster you kill a boss the more points you get. Bombing is encouraged. If a pattern looks too hard to dodge then just bomb the crap out of the boss and/or cancel all the bullets with the concept reactor.
Dodging is important in this game, but not as important as it might look at first.
And here's my highest score from earlier:
503,801,152 - ZenErik - stage 5 (final boss) - Miria - PC
I think I may take a day or two off from the game so I don't get frustrated if I don't get the 1CC on my next few tries.
