Was? You beat it?
I beat it once, but it was close. I used the Blade instead of the duck gun since it's lvl 2 version has the highest possible DPS in the game (although difficult to use) and it turned the eye block and the final boss into swiss cheese. Apart from that I pretty much took my time using the Bubbler to kill things slowly but surely. The second room is the killer, those blocks do massive damage for some reason.
I replayed it again and I think I forgot to do something since I didn't get to Hell again. Rocket v2.0, check, curly rescued and revived, check, spur obtained, check...
I dunno, I came to the Plantation and she wasn't on the bed. I guess I forgot something.
