Strange there isn't a thread for this yet that I can find, since it seems to take a fair bit of inspiration from Slay the Spire, known GWJ favourite. If you're like me and didn't quite get along with Slay the Spire for any number of reasons, this might appeal more.
This is a party based game for starters, initially you have 3 characters to go a-roaming with, you can sub in 6 other unlockable classes as you progress. I think the aesthetics are superb, the comparison that keeps jumping out to me is Gloomhaven of all things. It also has a similar item system to Card Hunter, where your ability cards are sourced from the items equipped to your character. All in all, it's an odd mix of inspirations and mechanics, but if it sounds appealing, the quite thorough How-To vid the developers released might convince you to give it a try, it worked on me.
