I'm curious about this game, but it won't show up on my phone. After quickly going through their site and Facebook, it does appear this is in alpha and only for android. The app market release must have been a mistake.
From poking around too, this appears to be F2P with some sort of crystal system; i assume you pay for crystals and get stuff.....ugh. This is starting to seem like another strategy game i recently liked; Lionheart Tactics. That game had very good art/concept/core gameplay, but poor F2P mechanics making it almost impossible to do anything without spending truckloads of money.
I'll keep an eye on this one, but i fear it may be a pass.
