- When you're out of coins, highlight the pass button so you know to click it - When it becomes your turn in the shop phase, do some big animation of "your turn" across the screen or something, with a sound. It's easy to not realize it's your turn right now. - I found one occurrence of the rock animation not playing for the opponent. It was deterministic for this battle (if I rewound and replayed, it still skipped) but it worked in other battles. - Under the hover state of the card, have a explainer box for the trigger - In the shop, the coints you have remaining should be big golden discs above the buy row, instead of a little icon in the toolbar. - The squirrel card has two colums to list it's two abilities, but we should just show them stacked vertically instead. - The crocodile didn't seem to work. I played my last pet, and my opponent had a crocodile set aside, but it didn't roll the rocks. - If you have lots of apples, they can go off-screen when they stack. Maybe make the play area larger?
