This key is part of Killer Bundle 6, from Bundle Stars. Since I'm not interested in it, there's no reason in having it laying around when someone could enjoy playing it right? :D

Horizon Shift is an explosive wave based single screen shooter with a ton of new ideas and platformer elements. Do what it takes to protect your horizon from the ever encroaching enemy attack!

NO THANKS NEEDED!
