I don't know why you're not getting more indie love. Your game looks so fun and hilarious. I do wish the bosses were more ludicrous, like with giant heads and robot arms and stuff, but that's just MHO.
I tweeted, FB'd and G+'d you today, hope you get some last 48hr funding.
PS I love the looks of "Under The Ocean" too!
Actually I am still playing with the idea of going metal slug with giant bosses and stuff VS megaman with pretty normal sized bosses - The only reason I am leaning towards megaman styled boss fights so far is I have pretty much lifted the whole "get the bosses weapon" from each leader so It kind of works. That being said I think I will have a larger boss towards the end but it probably wont be the norm.
That Hitler boss battle in the latest video is kind of a bad example - it was the first sort of prototype boss fight and isn't that impressive - probably a better one would be the Kim Jong battle - or the Stalin battle. Either way Its early days for the boss fights, I will be revising them before the demo goes out.
Also I am considering beefing up the co-op play with a bit of a Mario 2 styled pickup system - so one of the players can forgo there weapon to pick up high powered explosives/door breaches/etc and carry it while the other player covers them. I think it may add a bit more interest and break up the whole run and gun with a bit of co-op strategy, as it stands the only other co-op element ingame is the dragging your wounded friend around once they are "killed". Also maybe take a note from L4D with the whole -one player works the "progress bar item" while the other defends type thing coupled with some defensive type items could be cool also.
