It is cool idea. I find however really annoying that sometimes after killing enemy there appears more enemies or red crosshairs. Or rather that itself isn't such problem, but rather that there is no indicator whatsoever for that kind of behaviour. With proper indicator player could prepare for that, but now it just feels bad, when you thought you could end your turn to safe square or kill all enemies, but something like this happens. Otherwise really nice game. It would be nice to see your current deck and health when picking boons.
