This game is from 2015, a complete failure, especially from a gameplay perspective and also has no production value.

No one actually plays this game: http://steamcharts.com/cmp/388370,531640,364470,453480#1m (A comparison of 4 CCGS. None of them get close to the millions that play Hearthstone)
It's a dead game, with an all time peak of 69 concurrent players.

Do your own research by going to their discord, reddit, steam discussions, etc.

This ICO is an exit strategy to recover money. (Not that any of you care. Because hype, bounty, billions, NOW!!)
