Well, looks like the whip came in handy - fitting it was used to defeat its original owner, if indirectly.
Noticed that Infected Nester/Howard's colour schemes mached Wario/Waluigi's - nice touch.
That ending was creepy as all hell - impressive bit of meta-horror there.
(Saw the alien once again, too - its behind behind the pipe, at 1:04. As for the binary message in the outro, it translates to "HIS N@ME IS AN @CRONYM".)
