Balatro definitely inspired this (perhaps too much?!). Yeah I need a smoother curve to introduce items, and the idea behind them is that you pick the ones that synergize with the artifacts but really didn't have time to balance them, or introduce them gradually. Turned out that the +1/-1 were the most powerful items so decided to turn them into always available actions. I like the idea of previewing the effect of the items, will also try to reduce the random effects of many of them (or lean more into them, as I thought of an artifact which rewards you for playing many "shuffle" effects).
And mouse-only was included (also for mobile), but I introduced an artifact that broke this D:< I'm adding a button for next versions.
Thanks for your feedback!
