The designer's previous - and, as far as I'm aware, only other - game was set on a space ship and this game was designed to set parameters which differentiate it from the mass of medieval skirmish games. The creator's description on the Kickstarter page, which describes the game system in considerable detail, to the extent of making it essentially playable from this information alone, is followed by a detailed review from a disinterested party and links to YouTube videos. I'd strongly suggest it's worth a look.
