Oh man this one is good one but since English is not my native language it is really hard for me to find to what to write. I couldn't find even a single one. Maybe you can give hints a little bit, like in wordle. But cute game. Ah also fyi pressing esc is getting me out of fullscreen, so it is not working for deselecting the card.
I just wanted to add I passed all the tutorial without looking at it, and in the browser it didn't show me again the tutorial, maybe that is why I couldn't know anythigg.
