Now - a foreword; this is all going on the assumption that

the level codes at GameFAQs are accurate. I cannot find another source either confirming or disproving that assumption (though I didn't look super hard). I do notice two codes are an extra character long; these might be typos, or errors in the game.

But there's some interesting messages in the codes, for sure.

First, here's the list of codes, in actual level order (GameFAQs uses alphabetical order, which is slightly wrong here):

`02 STARTING`

51 to 59, these need to be arranged vertically:

`TSTDFWTO`

EMAWROAT

SETNTETH

ECRWHNSA

AOEAOJON

RDARSORG

EEDDEYTX

XSXSXXXXReading this top-to-bottom, left-to-right, and dropping the X's, this reads: "these are some codes that read downwards for those who enjoy that sort of thang" [sic]

Also, code 72 is WHEEEEEE. Not so much of an easter egg in and of itself, but both myself and GigaLem found this highly amusing.

I couldn't find any mention of this anywhere with a quick Google search. Is this known?
