I'm just going to say right now I hate Green's level. I posting a WIP, but really eveything after the second weapon switch is going to be redone. I thought it was weird that bosses only take damage every other frame. I also thought it was strange that my boss fights were going slower than Mike's speedrun even though I was basically attacking the bosses non-stop with a high powered weapon. It turns out that each player damages enemies every other frame and the registered damage alternates. I bet you if this were a one player game, the damage would happen every frame. Anyway, that means attacking the boss with both players will be twice as fast, considering, I can't throw in this level nor hit the boss with any body attacks. This of course changes my strategy a bit.
Let's see:
Weapons I know cause 4 damage every other frame:
force + force
fire + chaser
fire + lightning
chaser
I actually have a few viable options for player 1's weapon.
I can keep the force + force. It's a strong fast weapon, good for taking out multiple opponents, but can't be used at the same time as fire + chaser because of the lag. (actually fire+chaser sometimes causes lag all by itself) However, it can be used to dot i's when I'm writing, although it goes by so fast you barely see it.
I can switch for lightning + chaser. The manipulation to get a chaser out of the bird isn't that hard. i know how to do it. Lightning +chaser is a new weapon, and gives me a lot of options to switch to another new weapon in the next stage (double lightning, star chaser, force chaser, and lighning chaser are the only weapons I haven't used yet). If I use this, though, both gunners will be using chaser for most of the boss fight. (Might not be that bad. Chaser doesn't require that much processing power, so lag will be less of a problem)
I can also get force + chaser. This will allow me to dot my i's still (although it will still probably go by too fast) lag might be a problem with this one, but for the bosses, I'll be using the chaser part anyway because force + chaser has pretty much no strength.
Either way, it's still going to be another long hard trek through the last part of the level.
