Maniac mode... wow. 4 tries to get the 1CC with Phoenix - only 3 ships left in stock. Definitely a challenging mode that I'm sure is much more difficult with the Rynex ship. I'll be tackling that one soon...
Phoenix - Maniac
Final Score: 22,985,100
I had a quick go with Neo Style. Didn't notice any real big changes until I got to the ocean stage - where the missiles coming from behind, in the beginning, can only be destroyed with certain weapons. Didn't continue on from there but I'm betting Neo Style on Maniac mode is absolutely nuts.
Anyone want to post up their favorite stage orders? Here's mine with justifications

:
Phoenix - Flame -> Jungle -> Ocean
This is a good route for Phoenix because you get the shield right at the beginning - no missing the stage should be no problem since you always have all weapons in stock. The shield always lasts me through Jungle and I replenish it with the shield at the end of the stage. The Jungle boss almost never scores a hit, so I start out the toughest of the first three stages - Ocean - with a full shield.
Rynex - Jungle -> Flame -> Ocean
Jungle is the easiest stage - and since Rynex doesn't start with all weapons in stock it's the best level to fill your stock. Flame gives you the shield in the beginning and I usually only take a hit or two throughout the stage... Ocean is a bit rougher with Rynex as you might guess
Edit: Score was actually 25,985,100... there must be some sort of bonus added to your score in Maniac after defeating the final boss (ships left in stock?)
What more can I say I wouldn't be here today if the old school didn't pave the way.
