That was kind of a cliched start, but the bit where the rat started chatting him up with that totally un-rattish voice from out of nowhere - that was pretty cool. And silly. But definitely cool.
Would the game make good LP material? The rerun of your Legaia LP is just about done, so this could be a funny one to consider doing in the future. It looks like it has sort of weird-but-fun mood going for it.
... Okay, what the flarg, I just checked the TVTropes article and it says the quest eventually turns into a search for giant fruit? That is... not what I was expecting. I won't be getting it since I don't have a console, but my weirdness detector is starting to buzz showtunes and my curiosity is definitely piqued.
