Oh... damn, my bad. Too early in the morning to actually read I suppose.

It was bumped on REEEEEEEEEE, so I thought it was new news.
I kinda gave up at the final boss.. I dunno if I should just suck it up and add a handicap (like an extra life or two) just to beat it.
The key to the last boss(es) is to just focus on one of them at a time. Whoever
doesn't jump into the robot crab tank thing, just stay on top of them, but let them come to you on the far left or right of the screen. Should be able to dodge the claws from it in those areas easier. Once they're down, use the same method to just focus on the left or right claw after it does whatever animation and moves back to it's default stance. Rinse and repeat.....
... of course, now with the last big update they made, they completely and utterly fucked up the last stage with it's new enemy placement and spawns. It's now a slog that comes off more annoying than challenging.

Not sure why they messed with it. It's like a randomizer was used and left it in this random state. They really kind of fucked it up.. Wish I got the trophies prior to it. Hope it gets fixed down the road.... still love playing it from time to time.
