Maybe I'm just really bad at this game. But in dungeons like the Labyrinth and Shifting Passages, which have an extra boss monster in them besides the "main" boss, it seems that I can just barely scare up the resources to defeat the MAIN boss, let alone the extra one. And that's assuming I don't get Frank or Super Meat Man or something similarly difficult.
So I just have to wonder, why do they need to be there? I've been out of the loop for a few patches. Were there significant numbers of people complaining that this game wasn't hard enough?
