2015 Steam Winter Sale ARG (w badge info)-Follow Gingerbread Jake's clues [comic link still alive!]

oh man.
:o

A few sleuthy people have discovered clues and hints in this year's winter sale
and have found breadcrumbs left behind by Gingerbread Jake.
Follow along to see what was decrypted!
(Now with Red Herring Badge)

Gotta say, it's pretty damn impressive how people are decrypting the clues;
even more impressive is seeing people work together to solve them!

update 1:
go to Hitman: Codename 47
type search; push enter
input the code from the winter sale comic cover's barcode (now removed): 94050999014715

update 2:
inputting the code you get from update 1 {ic/4f21ca7} into winter comic url gives you this
4f21ca7 {filename 1fce82a72c633.wav}
A man saying "I was on the right track, I could feel it. Tomorrow, I was going to search again" The .wav is from the 24th

update 3:
"The Blitzen Incident"
http://store.steampowered.com/search/?term=blitzen yields Grim Fandango
type search; push enter
input the club code from winter sale comic: "HOT TODDIES AND MASERATIS"
now we're in Undertale Hmmmm.... o_o

update 4:
"Bullet Hell" is a tag on Undertale's app page.
on Undertale's page
type search; push enter
input "bullet hell"
now we're at Ikaruga

update 5 interesting Valve employee activity:
The Valve employee ChrisK/FireSlash has the "Red Herring" badge with the description "ARG?"
On his profile there is a (presumed) hash: 2cdeda75c0afb5c4a7a45dfe978315f6.
His last played games are: Undertale, Ikaruga and Ghost in the Shell: Stand Alone Complex - First Assault Online

update 5a:
ChrisK's profile went private for a little while, then went public again- this time with his badges all hidden/wiped xD (maybe GitS is the next pitstop)

update 5b:
ChrisK's badges are back now - he has modified his profile to say "This is just a profile" lol. Red Herring, perhaps, but Undertale -> Ikaruga is still pretty intriguing

update 6:
Trading Card 7 (Taffy) has Dungeon Master Symbols "Lo Ya Gor Ku"
Inputting it into a winter comic url gives you this:
LoYaGorKu {filename: loyagorku.wav}
rough translation:
忘れられた道が障害と報酬につながります" (wasurareta michi ga shougai to houshuu ni tsunagarimasu)
"Forgotten road will lead to failure and reward "

update 7:
Spectrogram analysis of LoYaGorKu {filename: loyagorku.wav} yields 1v7531
On Ikaruga
type search; push enter
input "1v7531"
Red Herring ARG? Badge unlocked.
via combatbeard: what is this
Doesn't seem like we're through
Seems like this is the failure (dead end) and reward for following the forgotten road (Blitzen incident)

If you're having problems getting the badge, you might have to disable enhanced steam

update 8 theories:

holiday profile backgrounds have changed with possible hints to some islands and we might have some coordinates.

There is also the "Twinkle" train theory (search twinkle on steam) http://store.steampowered.com/app/222621/
Watch video. From description: "Save Christmas
Take on a series of fun and entertaining missions, over the mantelpiece, under the Christmas tree and across the piano, uncovering secret routes and finding hidden treasures."

update 9:
Looks like this might squash some HL3 rumours:

update 10 theories:
Binary code in the last comic page. Look at the lights
The backgrounds used on the main store page match some of the pages in the comic:

update 11
Via bruteforce, a new wav file was found using Trading Card 6 (Sending a Message)'s clue
(In retrospect, "F" is the 6th letter in the alphabet - adding it to Trading Card 6's clue gives us 794E2CEA991F)
http://store.steampowered.com/wintercomic/794E2CEA991F {794e2cea991f.wav}
"I've been to Lima four times, stayed at all the best hotels. I used to go to dance halls and tango with Mary Carmen until the sun came up. thud The bravos and accolades would echo and echo until the boys in uniform shut us down."
Filter for NATO phonetic alphabet clues and you get LLLLHTBEEU (anagram of BULLET HELL [the code word that led us from Undertale to Ikaruga])

update 15:

With the Winter Sale over, nothingtoseehere.js and http://store.steampowered.com/wintercomic/ are gone ...
Wonder what the solution to the ARG was :(
http://store.steampowered.com/wintercomic/ is still alive! :D
There may be hope yet; but without the nothingtoseehere.js secret search script, I wonder if a solution is still possible

update 16 theories:

Potential link between Gingerbread Jake's clue map and a map of the North Pole
