Release: A Hat in Time - Seal the Deal DLC

Sitting on a cornflake, I am the walrus.
Seal the Deal, a new DLC for the delightful action/adventure Hat in Time, is now available, DRM-free on GOG.com.
NOTE: Owners of the base game can claim this DLC for FREE until September 14, 6pm UTC. This time limit does not apply to Kickstarter backers.
Hat Kid goes sailing! On the absolutely iceberg-proof vessel The Arctic Cruise, carried by a wave of whimsy, charm, and lovely seal-iness. Besides this brand new chapter, this DLC brings a tough-as-nails mode called Death Wish, six new Time Rifts to adventure through, plus a hatful of new outfits, dyes, and flairs!
Additionally, Hat in Time just received a FREE update adding a co-op split screen mode where you can play alongside the cheeky Bow Kid
