I'm enjoying this game so far and look forward to further development.
The difficulty level is about right for casual play and I like the reveal-to-inventory-to-deck mechanic. There are some balance issues with cards, though nothing game-breaking: both Anticipate++ and Apple++ pale in comparison to simple (and common) Green Tea, etc.
One thing that's really throwing me though is that cards are drawn with replacement, meaning that my hand sometimes fills up with cards that are difficult to play—in particular things like Slam in the Barbarian deck, which can easily get you killed. If cards were instead drawn without replacement, I could at least rest assured that, e.g., both of my Slam cards are already in my hand and I won't see any more.
Edit: Corrected card name from Bash to Slam; guess I'd confused it with another game. Same idea, though.
