Hey guys! I had the honor of impersonating Lake for Scojo's ongoing Impostor prompt! I went a little bit haywire and managed to take Lake's identity with this Rat Run puzzle!

Ratfinkz, the lovely rat in r9c6, just watched Marty, the marginally less lovely pile of squares in r9c9, place a 3 in his corner. Ratfinkz realises that this means Marty... is the impostor. Ratfinkz now has to run to the emergency meeting button in r1c1 so the crew can vote Marty off the ship.

Marty and Ratfinkz can travel orthogonally or diagonally, provided they do not run into any pink barriers (this includes corners). They have agreed to observe basic path etiquette, and so their paths cannot cross, cannot branch, and cannot cross themselves.

Marty indignantly races Ratfinkz to the emergency meeting button. As Marty runs along, just to spite Ratfinkz, he puts a 3 in every box corner he visits (including corners not on the edge of the grid). Marty can only run to a digit of the opposite odd-even parity of the cell he is currently on, since he is two-faced.

Ratfinkz, meanwhile, is trying to be quiet, and so every digit she visits must differ from the last by at least 5. Get it, cause whispers. Also her starting digit is equal to the number of boxes she will travel across.

Marty and Ratfinkz both end up within one step of the emergency button! The winner is the one whose path actually ends up at the button, obviously. But who won the race? Only you can find out. Okay bye.

Oh wait I forgot about the dots. So the dots don't do anything for the paths, but white dots indicate a difference of 1 and black dots indicate a 2:1 ratio. They are otherwise just sitting there.

Okay bye actually. Oh and normal sudoku rules apply i suppose.
