I think the game is feeling pretty good. There are a lot of interesting decisions to make and enough tools to consistently beat the boss even with bad rng (and it's often a close fight, which is good I think).
There was also something I hadn't noticed before about the number of cards played per turn. When I first played, I naturally was playing cards to address everything visible, and this is why I mentioned feeling like I needed to play safer. But then I realized you'd almost never want to play more than 1 card at a time anyway, or just enough to meet the draw card tick. Having more options is so important and there doesn't seem to be a reason to play more cards than that (or I haven't noticed it yet). Seems like it would be cool to have incentives for playing multiple cards on a turn. Do you have ideas or plans for that?
