This is quite a good game, but has a very frustrating learning curve at the start. I bet it would be more accessible if you added a tutorial and a relaxed mode, which leaves out the random negative events and makes the score requirement more forgiving. As shuffles are quite necessary sometimes, you could add a manual shuffle button to the relaxed mode, but have it be on like a 10-turn cooldown after use.
One bug I found: Sometimes you have no stones in hand, but you can't pick up stones from any circle (and there is no special stone selection). This softlocks the game.
