Hmm. I've 1cc'd with everyone now (well, I still need to do R.A.D., but whatever) and I still haven't gotten the free play, so I guess I'm still under 5 hours. I'm not sure what everyone's having so much trouble with.
I really wish I had a video capture capability of some sort to just make up some quick videos (that youtube link earlier in the thread is pretty bad), but I'll try my best to just give general hints instead.
1) Like a lot of shooters, dying is sort of a double-whammy since your guns are going to be crap upon resurrection. I know it doesn't really help to say "just stay alive," but you'll find it really helps to hang on when you can instead of viewing your 3 (or however many) lives as one big energy bar. Know where all the health regeneration points are, there's a lot of them! This can really help you to focus on a comeback if you make some mistakes early on.
2) For the record, I use:
Ruby/RAD: Type B
Tempest: Type B
I'm not sure why anyone would use other weapons, but apparently some people do.
- Realize that Ruby's little probe/latcher thing can eat bullets, shoot it at any incoming fire you can to reduce dodging needs.
- I don't like to use bombs unless necessary, they are more useful as shields in most cases, and there are several areas where you can use them to destroy ships while concentrating fire on other places if you have all three.
- Don't forget the little bumper-flip move for Ruby in a pinch. You only lose a very little bit of health, it is always better to use this than to actually take a lump from pretty much anything in the game.
3) Everything always happens in exactly the same way. Don't try to beat this game on sheer reaction times or innate ability, just memorize what happens in the hard parts and use that knowledge to easily take care of things. If you already know what's going to happen, it isn't that hard to deal with.
4) For stage 4, (this seems like the one most people have trouble with?) try memorizing where the snake/trains are coming from (first one comes from the top, second from the right, etc) and shooting right at the head the moment they appear on the screen. Destroying them immediately is your highest priority on this stage.
As mentioned before, dying will make destroying things in time very difficult on this stage, so losing one life will start avalanching with others.
I usually just use bombs on the very last section where the four vertical snakes with lasers go by since the stage 4 boss is so easy anyways. That's probably the hardest part anyways. There's two life-restoring pellets at the end if you've already used your bombs, though, so it's not a big deal.
For the mid-bosses, realize you can go around the ship and shoot from the rear when he does his gun-shooting. Makes it faster and you totally avoid the bullets.
5) Just FYI, you can position yourself so that you start inside the "square" of the first boss' opening formation and blow a bomb to do massive damage. You'll probably take a hit on the way out, but it's a small price to pay to just get this easy time-waster out of the way that much quicker, imo (for those sick of plowing through stage 1 just to get a shot at later stages, etc)
Other than that, I really don't know what to say.
Hope someone can at least find a part of that useful in some way. Good luck!
