I got through most of the game, though I did not quite complete it. The game mixes Civ-like unit movement with Slay the Spire-like deck building. Each of the four characters has a radically different way of playing, which is nice (though I generally avoided the fourth character that used ranged magic). The game has a limited scope, which is to its benefit. Even at its current length, I felt I had sufficient experience with it that I was okay putting it down. At the beginning of the game, figuring out which card combos work best was fun. There was still mystery in choosing. As I got closer to the end though, I found that there were game-breaking card combos that you could reliably get on most characters. These combos trivialize the game. I would say to avoid them, but they are hard to avoid because they allow you to meet all of the game's goals.
I would say this game would serve as an interesting entrance into the genre, but there is not enough polish or content there to stick with it long term.
