Monster Party Part 3

And you all thought the sewer level was the worst level of the game, well when you encounter the sewer level so soon into the game, obviously that's not the case. No no no, level 6 on the other hand, THAT... is one of the worst levels (and that's just if you know what you're doing, otherwise it's possibly the... worst... possible... thing!)

Afterwards, Eizen tries to take out one of the game's only optional bosses, and from there it's just a downward spiral. But at least Eizen makes it to the final level and it starts to go back uphill from there, right? ...Right?
