Solid start, but 3x games in a row I didn't get a single healing item in the first battle or in the opening hand of the second battle resulting in a round 1 loss. Subtly weighing the RNG in the player's favor when at low health will increase the quality of the Play Experience.
As a game dev, this is very possible, but I personally think it would be more interesting to make the player make conscious choices about how to build their deck. Look towards other roguelike deck builders (slay the spire, cough cough) on how to execute this well. But this is an awesome foundation and I really do hope Amsern Studio keeps developing this, I'd gladly pay money for a more expansive and polished version of this. Awesome!
