Thanks for the detailed feedback. It helped me see that the tutorial was moving too quickly and wasn’t clearly connecting your actions to their results.
I’ve updated it to explicitly introduce itself as a tutorial, identify Spades and Clubs as enemies, and explain what Diamonds and Hearts do. Instructions stay visible while you decide, visual highlights guide your attention, and explanations wait until the hand has finished resolving so you have time to see what happened. It also clarifies Weapon × Mult and the difference between damage and score.
Your Straight/Flush example exposed an unintuitive rule. Straights now require four or five consecutive ranks, allow an extra card without breaking the sequence, and take priority over Flush.
I’d love to hear whether the updated version makes the first attempt clearer :-)
