Thanks for the thread! I would like to be clear that Sky Gnomes: Battles is a completely new, stand alone game. It IS included as a free, separate mode in the paid $.99 version as a convenience to those early adopters
About the only thing that's the same is really just the actual racing mechanics.
But as far as the game itself goes, I'm using the term "Mario Kart battle mode meets Words with Friends" as a descriptor. This game focuses on turn based battles and challenges, using offensive and defensive items to get the win. Things like machine guns, rockets, harpoons which slingshot you ahead, shields, and tons more items. There's a lot of strategy in the battles, and we have a Starcraft II esque ladder system in place for skill based competition!
The other cool thing is that as you're fighting back and forth, you actually can affect the recorded runs of your opponent! There's a ton of interaction for being a turn based action game
Anyway, its free with minimal IAPs
(basically new characters only), so we hope you'll give it a shot!
